Q15 of 37 Page 1

An equilateral prism is made up of material of refractive index. The angle of minimum deviation of light passing through the prism is ____ .

According to Snell’s law


Relationship between Internal angle of Prism (A), angle of minimum deviation (D) and refractive index () of Prism



Here


As we know Internal angle of Prism (A) is . Then,




Thus, the angle of minimum deviation of light passing through the prism is 60˚.
