Answers
Hi Mate,
Below is the explanation & reason why sun looks reddish at sunrise & sunset.
During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the redlight, which is the least scattered, enters our eyes. Hence, the sunand the sky appear red.
Hope this helps.
As day breaks, a reddish-white ball of light that we call the sun, rises. This red haze gives way to a golden-white sheen as the day advances and reappears when the sun sets in the evening. Does the sun really change colours, or does it only seem so? The explanation lies in-between.
Light from the sun consists of three kinds of radiation – ultra-violet rays, visible light and infra-red rays. Unlike visible light, ultra-violet rays and infra-red rays cannot be seen.
The visible light’s rays are white and consist of seven colours – violet, indigo, blue, green, yellow, orange and red (known simply as VIBGYOR).
The earth’s dust, gas and air particles scatter the sun’s light in different directions. Violet light has a peculiar property due to which it gets scattered the most. Red light gets scattered the least.
