A wavefront is a surface (a) perpendicular to the direction of propagation of light. (b) parallel to the direction of propagation of light. (c) without any specific orientation with direction of propagation of light. (d) which has nothing to do with intensity of light.

Answer: (a). A wavefront is the locus of points vibrating in the same phase. Rays (direction of energy flow) are always normal to the wavefront. So the answer is (a) perpendicular to the direction of propagation.

Show answer and solution

Answer: (a)

A wavefront is the locus of points vibrating in the same phase.
Rays (direction of energy flow) are always normal to the wavefront.
So the answer is (a) perpendicular to the direction of propagation.
