A light beam in air strikes the surface of water at an angle of 26° with the normal. When it enters the water it bends toward the normal, making an angle of 19° with it. The velocity of light in air is approximately 300,000 km/s. What is the approximate velocity of light in water?

sin i/ sin r= Vi/Vr

A77,197 km/s

B222,803 km/s

C278,437 km/s

D340,625 km/s

Medium 1 is air, and its index of refraction rounds to 1.00. If the angle of incidence is 61° and the angle of refraction is 45°, what is the index of refraction of medium 2?

sin i/sin r = nr/ni

B1.00

C1.24

D1.35
