could you answer both of these. i got work due and its in 30 minutes. thanks in advance :)

A ray of light travels from glass to air with an incident angle of 37 from the normal. What is the reection angle? Assume \"glass = 1.50 and air = 1.00. A laser beam is nicident at an angle of 38.7" on a 0.0253 m thick piece of glass with a fully reective coating on its bottom surface. Part of the laser beam is reected off the top surface of the glass at point A, and part is transmitted through the glass to point B where it is reected and sent out of the glass at point C. If both surfaces of the glass are at and parallel, what is the perpendicular distance d between the two outgoing beams? Assume ng1m = 1.50 and m3: = 1.00. a E 3 s s E a
