• 632 nm electromagnetic wave (ray) in glass arrives at the glass-water interface at an angle of 48deg with the normal (travelling from glass to water). The refracted ray, in water, makes a 72deg angle with the normal. The index of refraction of water is 1.33.
• (a) What would be refractive index of glass?
• (b) What would be the speed of light in the glass?
