Light waves travel in vacuum along the y-axis. Which of the following may represent the wavefront?

A

y = constant

B

x = constant

C

z = constane

D

x + y + z = constant

Text Solution

Verified by Experts

The correct Answer is:
A
As velocity of light is perpendicular to the wavefront and light is travelling in vacuum along the Y-axis, therefore, the wavefront is represented by y = constant.
