A flat piece of glass covers the top of a vertical cylinder that is completely filled with water. If a ray of light traveling in the glass is incident on the interface with the water at an angle of θa = 36.0 ∘ , the ray refracted into the water makes an angle of 50.0 ∘ with the normal to the interface.
