What is the radiation pressure 1.2 m away from a 600 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.

Step 1
2 m. We can use the inverse square law, which states that the intensity of radiation decreases with the square of the distance from the source. I = P/4πr^2 where I is the intensity, P is the power of the lightbulb (600 W), r is the distance from the bulb (1.2 Show more…

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)

A 150-W lightbulb emits 5\% of its energy as electromagnetic radiation. What is the radiation pressure on an absorbing sphere of radius $10 \mathrm{m}$ that surrounds the bulb?
