Sunlight strikes a piece of crown glass at an angle of, Ask an Expert

Academics

Sunlight strikes a piece of crown glass at an angle of incidence of 38 degree.

A) Find 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.

B) The ray now travels inside the glass. Find 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?
