Vedclass · Answer

(A) The wave front is defined as the locus of all points having the same phase of oscillation.For a light wave traveling along the $x$-axis, the direction of propagation is parallel to the $x$-axis.The wave front must be a plane perpendicular to the direction of propagation.Since the wave travels along the $x$-axis, the wave front must be a plane parallel to the $yz$-plane.The equation of a plane parallel to the $yz$-plane is given by $x = 	ext{constant}$ (e.g., $x = a$).Therefore, the correct option is $A$.

$A$ light wave travels in a vacuum along the $x$-axis. Which of the following may represent the wave front?
