Question

A ray is _______________________________________ and illustrates the wave nature of light. Group of answer choicesperpendicular to the direction of energy flowalways parallel to other rays .perpendicular to a series of wave fronts .illustrates the wave nature of light .

Answer 1

Given:

Some statements on a ray of light

To find:

The correct statement

Step-by-step explanation:

A wavefront is a locus of the points in the same phase in a wave. The rays are always perpendicular to the wavefront and show the direction of energy flow.

Hence, the correct statement is 'a ray is perpendicular to a series of wavefronts.
