Hi there, if you could solve it real quick. That would be very much helpful and appreciated. Thank you. I will give a good feedback too.

As shown in the figure below, a glass prism (n1 = 1.60) is immersed in water (n2 = 1.33). a) Find the exit angle 03. b) If you dissolved a substance in the water to increase the index of refraction n2, at what value of n2 does total internal reflection stop happening at point P? 60.0 P 01 n 2 n 1 02 30.0 03
