An early method of measuring the speed of light makes use of a rotating slotted wheel. a beam of light passes through a slot at the outside edge of the wheel, travels to a distant mirror, and returns to the wheel just in time to pass through the next slot in the wheel. one such slotted wheel has a radius of 5 cm and 500 slots at its edge. measurements taken when the mirror was l = 500 m from the wheel indicated a speed of light of 3.0 x10^5 km/s.. what was the (constant) angular speed of the wheel? . (b) what was the linear speed of a point on the edge of the wheel?
