Light and Colors
Introduction
Light is electromagnetic energy that can pass through transparent objects and empty space without requiring any medium for its transmission from one place to another. There arc different views about colors. Light in actual effect is a combination of different frequencies and various wavelengths. Feeling of a particular wavelength, having a typical frequency, by the retina and the mind is known as color.Spectrum:
In 1666 Sir Isaac Newton expounded the Principles of Gravitation and Theory of Colors. When the sunlight or the light waves. according to this theory, pass through a prism, they disperse according to their frequencies into seven bands and we know this grouping of waves. as colors, All the other colors arc shades of these seven bands of colors This band of rainbow colors resulting from the dispersal of light waves is named as spectrum.Violet. indigo, blue, green, yellow, orange and red, are the colors in a spectrum our eyes arc more sensitive for yellow and green colors and interestingly the sunlight also boosts yellow and green more than other colors.
Colors witnessed in a spectrum are only the visible part of the spectrum. The waves, which have wave lengths shorter than violet waves cannot be seen by our eyes e.g. ultra-violet rays, x-rays, gamma rays etc. Similarly the waves of larger wavelengths than the red also cannot be seen e.g. infra-red and microwaves.
It is not so that everybody can witness the colors other than the seven colors of the spectrum. there are people who can witness even the invisible waves of the Electromagnetic Spectrum.
Colors and optical system:
How do Vie see color? There are different views in this regard. The idea that is generally accepted is known as Classical Theory. Classical Theory was presented by renowned Physicist Mr. Young and anatomist Mr. Jlelm Holtz. This is also called Young Helm Holtz Theory. Hath these scientists were moved to see that only three colors are enough to form other compound colors.Three types of cones. according 10 this theory, arc there on the retina. One type of cones is sensitive for the wavelengths of blue color. other is sensitive for yellow color and third type of cones is to feel the red. The wavelength of the color falling upon the retina triggers the concerned cone and thus the particular color is sighted. All the colors arc witnessed because of triggering of two or three cones e.g, wavelength of purple activates the cones sensitive for red and blue. Resulting activation of these two cones we sec purple color.
Why do we see colors? Color, in actual fact. is that quality of the light which it expresses after mixing with darkness. We see an object black because it absorbs all the waves of the light and we see an object white: because it reflects all the waves of the light. We see an object red because it reflects the waves of the red color only and absorbs all the other waves. And, the same is true for all other colors.
Why are the colors? How do they form? What . . arc the primary colors? Exact situation is vet not clear. Some consider that there are four primary colors: some say these are three. And, according to few. black is the basic and primary color.
Spiritual Theory of Colors
which sight can perceive, as color. light precious stones and in the last stage calls it water. When we see in the space and the sight reflects back upon the screen of our mind. it creates an impression. This impression is conceived as sky blue color.
After raining, when the atmosphere is clear of dirt and smoke. the rays of the sky blue color change their hue according to their position. Here 'position' means atmosphere, which man terms high. low down. vast, near or away from the earth. These things make the blue color deep or light and so much so that it changes altogether into different color or colors. Between the earth and our range of sight there exist innumerable types of rays. The type of ray's is sighted as colors. The atmosphere is filled with many things besides rays of colors. which are responsible for changes in it. The scene before our sight includes light. oxygen. nitrogen. and other gases. Besides these gases some shades of different intensity are also there. Some other components also include in the sky blue color. These very components produce different types of colors. Here this must be kept in mind that the light and dark shades also play an important role in the making of different types of colors
What is the actual source of light? Man does not know it exactly The distance between the source of rainbow and earth is reported to be ninety million miles, This means that the colors seen so closely are originating at such a far away distance. It is bit difficult to understand that besides rays what other things keep on dissolving in the air exist in the atmosphere. The smallest particle of the rays reaching us from the sun is called photon.
In Sufism. the word 'aariz' is used for photon, Even the word photon does not cover the exact meanings. which the word aariz carries. but it is the only closest term that can give an occidental reader some idea of aariz. It is one of the characteristics of aariz that it has no dimensions and these arc so swift and fast that they come back from where they start their journey in the very same moment after covering. the whole cosmos. We cannot say what the status of photon is in this regard according to the scientists, but it is certain that aariz: travels through the universe at such an incredible speed that it reaches back. from where it starts it journey. in the very same moment after traversing the entire universe. Since there are no dimensions in the aariz. therefore, when they scatter in the form 0 frays. they neither collide nor replace one another.
Space. ill actual fact, is the contact aariz with anyone of the elements existing in the atmosphere.
What is this atmosphere'? Atmosphere is the division of colors. This division of colors is not happening because of the aari: alone; rather it takes place because of the loops produced by the aariz, When an aariz strike against these loops it gives rise to things like space, colors and other things.
Now the question is that how the loops are formed in the rays. We do know about the existence of stars in the galaxies: the stars which are considered to he the sun. The distance between two stars is estimated to be five light years at the least. Wherever the lights of the stars collide they form loops because 01 difference In their types. Our earth or other planets are also merely loops. which are formed in the colliding lights of the billions of stars in our galaxies. Wherever the lights of these stars collide; a loop is formed which. after accumulating more lights takes the form of a planet.
First of all a mixture of blue color. combined with many other colors, is received by man through his head and hair. These mixed colors keep on absorbing and i influencing the thoughts and feelings in him. The more one accepts the influence the more one is affected by It.
There- are billions of cells in the human brain. An electric current resulting from the frequencies of" rays of colors. flows through these cells. Thoughts keep on passing through the conscious and the subconscious and more through the unconscious mind. due to this current. Thoughts and feelings keep on changing continuously under the influence of the light and dark shades of the colors. A shade, after producing its effect, leaves its place so that another type of shade could take over. The replaced shades. if they are dark enough. transform into Our feelings and rest of thoughts dissipate into thin air.
Gradually man learns to connect these thoughts with one another. The thoughts, which arc not entertained, are altogether deleted. And. the thoughts that absorb in our mind become our acts and deeds. These very shades are responsible for the sorrows and delight that we experience. These make us happy or sorrowful according (0 (heir intensity. Discarded shades are discharged from the body system and which are absorbed and adopted. form our nervous system.
Since man being a biped, walks and moves around in upright position on two feel. therefore. these shades. first or all, affect his brain, Our brain has specific movements through which it causes our nervous system work for us. The hind portion of our brain: medulla oblongata, and the spinal cord play the key role in our nervous system. The sorrow and delight. which in fact. are a son of electric impulse, enters the nervous system through our brain and affects the whole of our nervous system.
The waves that enter the brain or bipeds me earthed through the feet after passing through the whole body. The weight and effectiveness of these waves arc not uniform for all the places in the atmosphere rather it varies from place to place because of their dividing nature As a result of this division the brain absorbs few shades more than others and the others are altogether left out.
If we look at someone's (ace intently. we can notice various colors on 11 and the most prominent of all is the color or one's eyes and that of the feelings which one experiences at that particular moment. Many a reflections from outside influence our feelings: some refresh us. some cause us to become pensive. some give us strength and some make us feel weak. All the brain work depends upon those much seen things. which gradually infuse in our nerves, sometimes it works correctly and at times it does not. The brain waves produce so many impressions on a face that virtually it seems impossible to read all of them but still a sort of film is displayed on the bee that informs us about the impressions transferring into the nerves.
