Energy of radiation incident on a perfect absorbing surface per unit are in unit time is 3.6J. The radiation pressure is:
Energy of radiation incident on a perfect absorbing surface per unit are in unit time is 3.6J. The radiation pressure is:
Show Hint
Pay attention to the surface type:
- Perfectly absorbing (black body): $P = I/c$
- Perfectly reflecting (mirror): $P = 2I/c$
- Perfectly absorbing (black body): $P = I/c$
- Perfectly reflecting (mirror): $P = 2I/c$
