Q: The photographs taken from a satellite show the sky as dark. This is because:
  • A. no dispersion occurs
  • B. no refraction occurs
  • C. no scattering occurs
  • D. no reflection occurs
Correct Answer: Option C - Scattering of light is the phenomenon that results the sky to appear blue. Fine dust particles in the earth's atmosphere scatters the sunlight. In the outer space due to absence of atmosphere scattering of light cannot happen. Thus, the sky appears dark instead of blue to an astronaut.
