Answer:
Explanation:
A wave is thought of as a disturbance or an oscillation traveling through the space-time, accompanied by a transfer of energy. The propagation of the wave direction a wave is always perpendicular to the direction of its oscillation. A wave does not move mass in the direction of propagation, but it transfers the energy
If a single crest occurs in more than one dimension, and at more than one place at a given time, then the set of all the points comprising a wave crest is known as the wavefront.
Therefore, in a plane wave, the wavefront is a plane in a 3-D or a line in a 2-D. In either case, the front is always perpendicular to the direction of motion of the wave.
