Question

What is a dual nature of light?

Answer 1

Hint: The two physicians MAX PLANCK and ALBERT EINSTEIN together explained the photoelectric effect by assuming that light was actually a steam of little particles or packets of energy which are called photons or quanta. But later scientists believe the light can be both wave and particle.

Complete answer:
Light consists of dual nature which means sometimes it behaves like a particle (known as photon), which explains how the light travels in straight lines. Sometimes light behaves as the wave, which explains how light bends (or diffract) around an object.

THE DUAL NATURE OF LIGHT IS EXHIBITED BY:
Photoelectric effect
Refraction and interference
Diffraction and reflection
Diffraction and photoelectric effect

The photoelectric effect is an example of light behaving as a particle (proton) whereas the diffraction and interference are examples of light acting as a wave. So it is confirmed now that light is dual nature , it can behave as a wave and particle there is no single physical phenomenon which describes the dual nature of light.

Note:
Light is electromagnetic radiation within the portion of the electromagnetic spectrum. The light is consist of seven basic properties i-e reflection of light, refraction of light, diffraction of light, polarization of light, scattering of light, interference of light, dispersion of light
