A 150-W lightbulb emits of its energy as electromagnetic radiation. The bulb is at the center of a perfectly light absorbing sphere of radius 10.00 m. What is the radiation pressure on the sphere’s interior?
Sunlight falls perpendicularly on a kite with a reflecting surface of area 0.75 m2. The average intensity of the sunlight is 900 W/m2.
What is the average force on the kite due to radiation pressure?
If the kite material is black and absorbs all sunlight, what is the average force on the kite due to radiation pressure?
A 150 W light bulb emits radiation with a power of 6.2 W uniformly in all directions. What pressure does the emitted radiation exert on a mirror at a distance of 1.0 m from the bulb?
