The sun appears red at sunrise and sunset while it appears white at noon, because
Correct answer: D. Of Scattering of light due to dust particles and air molecules.
- A. Of refraction
- B. It is cooler at sunrise and at sunset
- C. Of diffraction leading to red end of the spectrum reaching the earth.
- D. Of Scattering of light due to dust particles and air molecules.
Explanation
At sunrise and sunset, sunlight travels through a longer path in the atmosphere, so shorter blue wavelengths are scattered more and red light reaches the eye. At noon, the shorter atmospheric path makes the Sun appear nearly white.
