Vedclass · Answer

(B) The rising and setting sun appears red because the light from the sun travels a longer distance through the Earth's atmosphere when it is near the horizon compared to when it is overhead.According to Rayleigh's law of scattering,the intensity of scattered light is inversely proportional to the fourth power of its wavelength,i.e.,$I \propto \frac{1}{\lambda^{4}}$.Since the wavelength of blue light $(\lambda_{b})$ is much smaller than the wavelength of red light $(\lambda_{r})$,blue light is scattered away more effectively by dust particles and air molecules.Consequently,the red light,which is scattered the least,reaches our eyes,making the sun appear reddish.

The rising and setting sun appears to be reddish because:
