Radiations of intensity 0.5

W{m^{ - 2}}

are striking a metal plate. The pressure on the plate is

View answer and explanation

Correct option: A

0.166 \times {10^{ - 8}}\;\mathrm{N}{\mathrm{m}^{ - 2}}

Option A (

0.166 \times {10^{ - 8}}\;\mathrm{N}{\mathrm{m}^{ - 2}}

) is correct because the pressure is calculated as intensity divided by the speed of light when the radiation is fully absorbed.
