What type of experimental evidence indicates that light is a wave?

Short Answer

Expert verified

We discover the nature of light with the help of phenomena of diffraction and interference.

Step by step solution

01

Concept Introduction

A wave is a disturbance or variation in a medium that carries energy from point to point.

02

Explanation

Diffraction and interference help us understand the nature of light.

The number of apertures (of very small size) through which light is refracted distinguishes diffraction from interference. Lights diffracted apertures interfere with each other and create constructive and destructive patterns, and this proves that light is a form of a wave.
