Question

Explain why clear sky appears blue to a person on the earth & dark instad blue to passengers flying at avery high altitude

Answer 1

Dear Student

The sky appears blue to us because of the scattering of light of less wavelength by the minute particles present in the atmosphere of Earth but since as we go higher the atmosphere becomes thin and there are less particles of light so scattering does not take place thus the sky appears blue to them
