Answer :
The line drawn connecting the crests of several waves and perpendicular to the direction of wave motion is the: wavefront
The wavefront is an imaginary surface that is composed of all the points of a wave at any instant, this surface is defined as the line drawn connecting the crests of several waves and perpendicular to the direction of wave motion.
If the propagation velocity differs at many points of a wavefront, the direction and shape of the wavefronts may differ by the refraction.
What is a wave?
In physics, it is the propagation of a perturbation of one of its properties in space, which involves a transmission of energy without displacement of mass.
