What is Prism?
What is the cause of Refraction of light through a prism?
If you know then pls answer according to your understanding.

Answer:
An optical prism is a transparent optical element with flat, polished surfaces that refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The traditional geometrical shape of an optical prism is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, acrylic and fluorite.
Answer:
Q1 Ans
GEOMETRY
a solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
OPTICS
a glass or other transparent object in the form of a prism, especially one that is triangular with refracting surfaces at an acute angle with each other and that separates white light into a spectrum of colours.
Q2 Ans
The direction of light changes as it passes from one medium to another. In other words, light bends as it travels from one medium to another. When light waves travel from one optical medium to another, they get refracted due to difference in optical density of the two media.
