A beam of light passes from glass with refractive index 1.58 into water with a refractive index 1.33. The
angle of the refracted ray in water is 58.0°.
a) Draw a sketch of the situation showing the interface between the media, the normal line, the incident
ray, the reflected ray, the refracted ray, and the angles of these rays relative to the normal line.
b) Calculate the angle of incidence in the glass.
A small metal band is slipped onto one of the tines of a tuning fork. As this band is moved closer and closer to the end of the tine, what effect does this have on the wavelength and frequency of the sound the tine produces? Why?
