According to Huygens’ principle, every point on a wave
is a diffraction source. is the superposition of every other wave. is perpendicular to the rays of the waves. behaves as a source of new waves. Answer: D

When light undergoes interference, it can sometimes
increase in amplitude. cancel completely. Both of these. None of these. Answer: C

When light undergoes interference, it can sometimes
increase in amplitude. cancel completely. Both of these. None of these. Answer: C Explanation: Light can build in amplitude by constructive interference and can cancel by destructive interference.
