Question
Part A Estimate the radiation pressure due to a bulb that emits 25 W of EM radiation at a distance of 6.5cm from the center of the bulb. Assume that light is completely absorbed. Express your answer to two significant figures and include the appropriate units. P = Part B Estimate the force exerted on a fingertip at this point. Suppose that the area of the fingertip is 1.5cm2 . Assume that light is completely absorbed. Express your answer to two significant figures and include the appropriate units. F = Part A Estimate the radiation pressure due to a bulb that emits 25 W of EM radiation at a distance of 6.5cm from the center of the bulb. Assume that light is completely absorbed. Express your answer to two significant figures and include the appropriate units.
