Q. The index of refraction for violet light in silica flint glassis 1.66, and that for red light is 1.62. What is the angulardispersion of visible light passing through an equilateral prism ofapex angle 60.0° if the angle of incidence is 50.0°?

Q. A 2.35 kg mass is attached to a light cord that is wrapped around a pulley of radius 3.35 cm, which turns with negligible friction. The mass falls at a constant acceleration of 3.30 m/s2. Find the moment of inertia of the pulley.
