Q. |
In the absence of the earth's atmosphere, sky would appear – |
A. | blue |
B. | deep red |
C. | white |
D. | black |
Answer» D. black | |
Explanation: Sky appears blue because the tiny particles of the earth's atmosphere scatter the blue colour (short wavelength) of the sunlight more dominantly than other wavelengths. A blue sky is a manifestation of Rayleigh scatter. The sky would appear black in the absence of earth's atmosphere because there would be no particles to scatter the light. |
