Problem 3Q

Why is light sometimes described as rays and sometimes as waves?

Step-by-Step Solution:

Step-by-step solution

Step 1 of 1

There are two theories of the character of light. Particle theory and wave theory.

According to particle theory light is stream of tiny little particles. The tiny particles travel along a straight line. This straight line of light is called light ray. Einstein`s photoelectric effect proved that light is made of little particles.

When  the light is allowed to pass through double slits in young’s experiment, the lights passing through two slits interfere. Only waves undergo interference, so young`s experiment proves that light is wave.
