Could I please get some help with this problem and the key concepts, please and thank you
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, as in the figure, 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 5.17 cm and 150 slots at its edge. Measurements taken when the mirror is L = 550 m from the wheel indicate a speed of light of 3.00 x 105 km/s. (a) What is the (constant) angular speed of the wheel? (b) What is the linear speed of a point on the edge of the wheel? Light source (a) Number i 6) Number Light beam Rotating slotted wheel Mirror perpendicular to light beam Units Units î <>
