(b) Draw ray diagrams 3a (10 pts). A ray of light from air enters at 70° on the water (nw=1.33) and then refracts through glass (ng= 1.51). What is the angle of refraction in the glass? Water 3b (15 pts)). A ray of light gets reflected at a critical angle on the left side of glass slab and finally emerges out into air shown in the figure. Find the angle emergence (01)
