A fish tank made of crown glass is full of fresh water.
(a) What is the angle of refraction when the light travels from the air and enters the crown glass at an incident angle of 30.0°?
(b) Determine the angle of refraction when the light leaves the crown glass and enters the water.
(c) If the aquarium is full of saltwater, will the angle of refraction be greater or less than the angle of refraction for fresh water?
