Estimate the radiation pressure due to a ultra bulb that emits 24.89 kW of EM radiation at a distance of 2.85 cm from the center of the bulb. Pressure is the average intensity divided by the speed of light. (c = 3.00 x 108 m/s)

Step 1
Given: Power (P) = 24.89 kW = 24.89 x 10^3 W Distance from the center of the bulb (r) = 2.85 cm = 2.85 x 10^-2 m Intensity (I) = P / (4πr^2) Intensity (I) = 24.89 x 10^3 / (4π(2.85 x 10^-2)^2) Intensity (I) ≈ 2.42 x 10^6 W/m^2 Show more…

Estimate the radiation pressure due to a bulb that emits 25 W of EM radiation at a distance of 8.5 cm from the center of the bulb. Assume that light is completely absorbed. Estimate the force exerted on a fingertip at this point. Suppose that the area of the fingertip is 1.1 cm2 . Assume that light is completely absorbed.

What is the radiation pressure 2.7 m away from a 315 W lightbulb? Assume that the surface on which the pressure is exerted faces the bulb and is perfectly absorbing and that the bulb radiates uniformly in all directions.
