What is the minimum angle of incidence

Reference no: EM13688390

Solve the following questions given below:

Question 1: Sunlight strikes a piece of crown glass at an angle of incidence of 31.5 deg. Calculate the difference in the angle of refraction between a yellow (580 nm) and a violet (410 nm) ray within the glass. The index of refraction is n=1.523 for yellow and n=1.538 for violet light.

Question 2: The ray now travels inside the glass. What is the minimum angle of incidence at which the yellow ray can hit the surface of the glass and become there totally internally reflected and not refracted?

I need experts help to solve the above questions.
