A beam of light in air makes an angle of \( 52.5^{\circ} \) with the surface (not the normal) of a glass plate having a refractive index of \( 1.69 \).

Part A What is the angle between the reflected part of the beam and the surface of the glass? Part B What is the angle between the refracted beam and the surface (not the normal) of the glass? Unpolarized light is incident on two ideal polarizing filters. The second filter's axis is rotated through an angle \( \theta \) relative to that of the first filter. Part A If the intensity of light emerging from the second filter is \( 1 / 5 \) the intensity of the incident light on that filter, what is \( \theta \) ? Express your answer in degrees to two significant figures.
