Light waves travel in vacuum along the

y - \mathrm{axis}

. Which of the following may represent the wavefront?

View answer and explanation

Correct option: A

y = constant

Option A (

y = constant

) is correct because a wavefront is a surface of constant phase, and if light travels along the y-axis, the wavefront is perpendicular to it.
