Critical angle in glass

WebA ray of light traveling through glass is incident on a glass/air interface at an angle below the critical angle for these two materials. If you were viewing this in the lab, you would expect to see light rays passing through Reflected and Refracted Rays point 1 only. point 2 only. point 3 only. point 4 only. points 2 and 4. points 1 and 3. WebDec 4, 2024 · Answer: Critical angle for water is 49°. The rays of light entering in water from below, suffer refraction. If these rays strike the water-air surface at an angle which is greater than 48°, they get totally internally reflected. These rays on emerging out of water, appear to came from the upper surface of water, which in turn appears silvery.
