what is prism?draw a diagram to show refraction of right ray through triangle glass prism? define angle of deviation?
Answers
Explain the refraction of light through a triangular glass prism using a labelled ray diagram. Hence define the angle of deviation. ... The angle of incidence and the angle of refraction are equal. The emergent ray bend at an angle towards the direction of incident ray. This angle is known as Angle of deviation.The angle of deviation is the angle between the direction of the refracted ray and the direction of the incident ray when a ray of light passes from one medium to another.In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application.
