Please answer this question number 24 with explanation....
Dear Student,
23. Option A .
The sun appears red at sunrise and sunset as red color (having the highest wavelength among all the colors in the visible light) scatter the least.
Explanation:
Light from the sun reaches our eyes through the earth's atmosphere. During this time, light rays get scattered in all directions by the gases and dust particles present in the atmosphere. The colors with shorter wavelengths are scattered more. Thus violet, indigo, and blue colors are scattered more. Among these colors, our eye is more sensitive to blue color. So when we look up the sky we see blue color is scattered everywhere and thus the sky appears as blue.
The sky appears blue during the daytime only. During sunrise and sunset, it appears red in color. This is because the distance between earth and sun is more during sunrise/sunset than during daytime. Thus during sunrise/sunset, light has to travel more distance to reach our eyes. Because of this, shorter wavelengths like violet, indigo, or indigo colors will be scattered away before reaching our eyes and the colors having longer wavelength( red) remains unaffected and passes through the atmosphere to reach our eyes hence making the sky appear red
Regards.
