Refraction of light is the bending of light as it passes through different mediums, such as air, water, or glass.
A prism is a transparent object with flat, polished surfaces that can refract light. It is typically made of glass or plastic and has a triangular shape.
When light enters a prism, it slows down and changes direction due to the change in medium. This causes the different wavelengths of light to separate and create a rainbow-like effect.
The angle of deviation is the angle between the incident ray and the emergent ray of light as it passes through a prism. This angle is determined by the refractive index of the prism and the angle of incidence.
Prisms are commonly used in optical instruments, such as eyeglasses, cameras, and telescopes, to manipulate and focus light. They are also used in science experiments to study the properties of light and in decorative items, such as chandeliers, to create colorful reflections.
