Question

Compare between the Ray and Wavefront. ​

Answer 1

Answer:

A wavefront is defined as a surface of constant phase. A wavefront is the locus of all points in the medium that have the same phase. ... The ray indicates the direction of propagation of wave while the wavefront is the surface of constant phase.

Answer 2

Hii friend...

ray :

the straight line path along which light travel in a homoginious medium is called a ray.

a ray is represented by an arrow head on straight line.

wave front :

the locus of all the points in same state of vibration for a medium is called wave front.

Or.

the wave front may be defined as the continuous locus of all such particles of the medium vibrating in same phase at any instant.

• the wave front is an imaginary surface of constant phase.
• phase difference between the two points of a wave front is zero
• as light is a transverse wave then every crest and trought is a wave front
• for a point source wave front is spherical.
• for a line source the wave front is cylindrical.

I think this will help you
