Question: An aquarium filled with water (nwater = 1.33) has flat glass sides whose index of refraction is 1.58. A beam of light from outside the aquarium (n air= 1.00) strikes the glass at an angle of 30.0 degrees as measured from outside of the glass to the incident light ray. What is the angle of refraction when:
A) The light rays enters the glass from air?
B) the light ray enter the water from the glass?
C) what is the critical angle from the glass to the water?
