Could you solve this problem please ? When a ray arrives at an angle ?i on a right triangle prism (?=25) in special glass (np =1.45), it emerges from the other side at an angle of 90.
When a drop of an unknown liquid is placed on the prism without changing ?i, the ray emerges with an angle of 60.
a) What is the angle of incidence ?i? b) What is the refractive index of the unknown liquid?
