A beam of light originates from point P in a 3 mm thick glass block. It undergoes total internal reflection at point Q and strikes point R a distance d=5.4mm.
A. If the glass block is in air, what is the glass' index of refraction?
B. Now, if the glass block is immersed in water (n=1.33) what is the new distance from point P to R?
