Which phenomenon is responsible for the red color of the sun at morning and evening?
A. Total internal reflection
B. Scattering of light✓ Correct Answer
C. Interference of light
D. Diffraction of light
💡 Solution & Explanation
Rayleigh scattering of sunlight by atmospheric molecules and fine dust particles causes shorter blue wavelengths to scatter away, allowing longer red wavelengths to reach our eyes during sunrise and sunset. Phenomena like total internal reflection account for optical effects such as mirages and rainbows rather than atmospheric reddening. Atmospheric scattering also explains why the daytime sky appears blue to observers on Earth.
