The reddish appearance of the sun at sunrise and sunset is due to (a) the scattering of light (b) the polarisation of light (c) the colour of the sun (d) the colour of the sky

Answer: (a). At sunrise and sunset sunlight travels a long path through the atmosphere. Rayleigh scattering ∝ 1/λ⁴ removes blue light from the direct beam most strongly. Mostly red light reaches the observer, so the answer is (a) scattering of light.

The reddish appearance of the sun at sunrise and sunset is due to

Show answer and solution

Answer: (a)

At sunrise and sunset sunlight travels a long path through the atmosphere.
Rayleigh scattering $\propto 1/\lambda^4$ removes blue light from the direct beam most strongly.
Mostly red light reaches the observer, so the answer is (a) scattering of light.
