The sun appears red at the time of sun- rise and sun-set. This is because:
- A. red colour is least scattered
- B. red colour is most scattered
- C. the sun is red in colour
- D. our eyes can sense only red colou
Step-by-step solution
At sunrise and sunset, sunlight travels through a thicker layer of the atmosphere, which scatters shorter wavelengths (blue light) more efficiently due to Rayleigh scattering. Red light, with its longer wavelength, is scattered the least, so it reaches the observer's eyes more directly, making the sun appear red.
