From the side, the beam can be seen by the blue light it scatters; but the light seen directly from the end is reddened after it has passed through the tank.
After days of rain, a patch of blue sky is a sight for sore eyes. We can see these different colours of light in a rainbow or when white light passes through prism. The result is the beautiful colours we see at sunset and sunrise and, very occasionally, a flash of green light. But why is the sky blue?
On a clear day, when there are no clouds and the sky is clear we see it to be blue. The reason for these arrangements is that like waves, the colors with the strongest energy are seen to be closest while those with a weaker energy are seen to furthest.
Therefore, light requires coming into contact with other particles in order for its colors to be visible. Light behaves the same way. Therefore, the reason why the sky is blue is because the colors in the light are dispersed by the particles in the air.
Blue light shorter wavelengh is scattered more than red light longer wavelength. It is, therefore, true that, in the presence of light, the sky is blue.
He showed that the amount of light scattered is inversely proportional to the fourth power of wavelength for sufficiently small particles.
Sunlight from the low Sun has to pass through much more atmosphere before it reaches your eyes meaning most of the blue light has already been scattered leaving just the red.
Where some of the stronger colors are absorbed, and the weaker colors widely scattered to be seen. The waves that are closer are stronger that is they have more energy and vigor when moving away.
This was demonstrated by Isaac Newton, who used a prism to separate the different colours and so form a spectrum. These colors are already in the light the raindrops or water in the air helps in making them visible.
Since light has to collide with the particles in the air to make its colors visible, not all colors are seen. The case was finally settled by Einstein inwho calculated the detailed formula for the scattering of light from molecules; and this was found to be in agreement with experiment.
The three different types of colour receptors in the retina of the human eye respond most strongly to red, green and blue wavelengths, giving us our colour vision. The white light from the sun is a mixture of all colours of the rainbow. When it rains there is a lot of moisture in the air.
Why the Sky is Blue Essay Why is the sky blue? The colours of light are distinguished by their different wavelengths. This is because, during the day, there is light from the sun while; at night, there is absence of light.
The blue color particles collide with the particles in the air and are scattered all over the sky. In some places, there are more than others, for example, near a factory there is more smoke and particles from the factory. Therefore, the colors in the light have different energy levels.
This can be demonstrated by shining a beam of white light through a tank of water with a little milk or soap mixed in. The folowing links are external You might also like: When the light collides with the particles in the air, these colors with the strongest energy and short waves are quickly absorbed by the particles in the sky and are not seen by the human naked eye.
The answer lies with how our eyes react to light. As, the waves move further from the source they become weaker because of the long distance their energy is reduced. In order, to answer this question it is necessary to understand what is the sky and everything in it. For instance, in looking at the rainbow the red color if furthest followed by orange, yellow, green, blue, then indigo and violet.Tag Archives: Sky Butterfly Nursery Rhyme- Butterfly English Poem For Kids Medium Grade/Class Nursery,Junior and senior Class Number of words 75 words Age group 2 to 5 years Why is the sky so blue and clear?
