Wave optics Introduction

In a one-word optics can define that science of light.
Light has dual nature sometimes it behaves like a wave and sometimes it behaves like a particle.
In other word deal with optics is the branch of physics dealing with the study of optical phenomena.
The phenomena like reflection and refraction are explained by corpuscular theory. but the phenomena like interference, diffraction and polarisation can not explain the particle nature of light.
In optics, we consider the light as a wave.
