Refraction of Light

Refraction is the bending of light

Refraction is the bending of light when it passes obliquely from one transparent medium to another due to change in speed. When light enters a denser

First Law

First Law: The incident ray, refracted ray, and normal at the point of incidence lie in the same plane. Second Law: The ratio sin i/sin r is constant

The refractive index (μ) is

The refractive index (μ) is the ratio of speed of light in vacuum to speed of light in a medium (μ = c/v). It can also be expressed as sin i/sin r. It

When light passes through a parallel

When light passes through a parallel-sided glass slab, it undergoes refraction at both surfaces. The emergent ray is parallel to the incident ray but

A prism is a transparent medium

A prism is a transparent medium with triangular cross-section bounded by two refracting surfaces. Light passing through a prism deviates by angle δ =
