MCQ
Wave front means:
  • A
    All particles in it have same phase.
  • B
    Few particles are in same phase, rest are in opposite phase.
  • C
    All particles have opposite phase of vibrations.
  • D
    All particles have random vibrations.

Answer

  1. All particles in it have same phase.

Explanation:

It is the imaginary surface representing corresponding points pf a wave that vibrate in unison. When identical waves having a common origin travel through a homogeneous medium, the corresponding crests and troughs at any instant phase.
