Why does the Sun Appear Reddish in the Early Morning?

Answer: At sunrise, the rays of light coming from the Sun need to travel long distances in the Earth’s atmosphere before they reach our eyes. On this journey, shorter wavelengths of light are scattered and only longer wavelengths reach our eyes. Blue has a short wavelength and red has a long wavelength, so red reaches the eye after atmospheric scattering. Therefore, the sun looks reddish in the early morning.
