Lesson: Deviation due to a Prism Physics
In this lesson, we will learn how to determine the effect of the shape and refractive index of a prism on the path taken through it by light rays.
A triangular prism has an apex angle of . Given that the angle of minimum deviation is and light rays deviate least through the prism at an angle of incidence of , find the refractive index of the prism to 2 decimal places.
A triangular prism produces a minimum angle of deviation of light rays through it when the angle of incidence of light rays onto the prism is . The minimum angle of deviation of the prism is . What is the apex angle of the prism? Answer to the nearest degree.
A very thin triangular prism has an apex angle of . The refractive index of the prism is 1.4. Find the minimum angle of deviation produced by the prism using the small-angle approximation. Answer to one decimal place.
