A beam of sodium light (landa =589 nm) is incident from air on a smooth surfac of water at an angle of 65 degrees (with respect to the vertical).
A) Determine the angle between the reflected and refracted rays.
B) Draw the interface, incident, reflected and transmitted rays.
C) Determine the wavelength of the light in the water?
D) Is the frequency of the light the same in water as in air?
