MCQ
In refraction, light waves are bent on passing from one medium to the second medium, because, in the second medium
  • A
    the frequency is different
  • B
    the coefficient of elasticity is different
  • the speed is different
  • D
    the amplitude is smaller

Answer

Correct option: C.
the speed is different
c
Since the speed of light changes in the second medium, its direction also changes.
