Question

Give the number of refraction occur when a ray of light passes through a triangular prism in your experiment

Answer 1

Answer is TWO Refraction.

Explanation:

A triangular prism is a glass prism that has three rectangular lateral sides and two triangular bases. Rectangular surfaces are inclined in nature, whose angle is named as the ‘Angle of the prism’.

- When a ray of incident light ray falls on a point A on one lateral surface of the prism, it undergoes first refraction and bends towards its normal.  

- Then the refraction ray traverses through the prism and again undergoes second refraction at a point B on the other lateral surface of the prism and comes out as an emergent ray.

Thus, refraction occurs twice for a ray of light passing through a triangular prism.
