The change of direction of light when light goes from one medium to another medium is known as Refraction or Refraction of Light. The ray of light changes its direction because of difference in speed in different media. These notes are based on the chapter Light: Reflection and Refraction from...

Refraction is the bending of light as it passes through a transparent substance. Water, sound, and other waves do it too. This bending had allowed the creation of magnifying glasses, prisms, lenses, etc. Here, the degree to which refraction occurs relies on the light's wavelength. Each li...
Reflection and refraction are almost the earliest means of light control used by human beings, which mainly involve the use of mirrors and lenses. The optical resolution of these devices is mainly dictated by the diffraction limit. Recently, along with the advancement of CMOS-compatible ...
Reflection of Light occurs when a ray of light approaches a smooth surface and bounces back. The laws of reflection determine the reflection of incident light rays on reflecting surfaces. Know more at BYJU'S.
In spite of these idealizations, the plane-wave model is exceedingly successful in predicting a large range of optical phenomena such as reflection/refraction at metallic and dielectric interfaces, diffraction by spectroscopic gratings, wave propagation in nonlinear and anisotropic media, etc. A ...
When light reflects off a surface, the angle of incidence is always equal to the angle of reflection. LAW OF REFLECTION Using the Law of Reflection The angle of incidence and the angle of reflection are always measured from the normal and not from the surface of the object. Why? Because ...
When comparing the diffraction angle as obtained from simulations to the one that is obtained in the experiment (measured in air), we apply Snell’s law such as to account for the refraction experienced by light when exiting the device. Device fabrication The device fabrication starts with ...
