Question

A Prism is made of glass of unknown refractive index .A parallel beam of light is incident on a face of prism. The angle of minimum deviation is measured to be 40 degree . what is the refractive index of the material of the prism ? The refracting angle of the prism is 60 degree . If the prism is placed is placed in water ( refractive index 1.33 ) predict the new angle of minimum deviation of a parallel beam of light.​

Answer 1

Answer:

the refractive index of the material of the prism is =1.5320

now if it is placed in water then the minimum deviation would be ....10.33°
