The refractive index plays an essential role in understanding several phenomena, such as dispersion and reflection. In this article, we will explore how to calculate the refractive index.

1. Refraction occurs when a wave, such as light, passes from one medium to another with a different index of refraction. 2. The index of refraction (n) is a dimensionless number that measures how much ...

For Higher Physics, revise how to calculate the expected direction of refracted rays using Snell’s law. Calculate critical angle given refractive index.

In this paper, the refractive index profiles of the periodically segmented waveguides (PSWs), which are fabricated in soda-lime glasses by the K/sup +/-Na/sup +/ ion-exchanged technique, are ...
