- A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction? Calculate to 1decimal.Calculate the critical angle for light to travel from glass (n = 1.56) to water (n = 1.33).2. A small light source (point source) is located in water (nr 1.33) at a depth d below the surface. Determine (a.) the critical angle for total reflection of light at the water-air interface (b.) the depth of the light source if an observer above the water sees an illuminated circle of 3m radius.

The light moves horizontally through the prism and strikes the right face at an angle of 30.00° to the normal. As the light leaves the prism it is refracted at the right face.
