Radiations of intensity 0.5 Wm-2 are striking a metal plate. The pressure on the plate is |
0.166 × 10−8 Nm−2 0.332 × 10−8 Nm−2 0.111 × 10−8 Nm−2 0.083 × 10−8 Nm−2 |
0.166 × 10−8 Nm−2 |
Intensity or power per unit area of the radiations, $ P = pv$ $ ⇒ p = \frac{P}{v}$ $ =\frac{0.5}{3×10^8} = 0.166 × 10^{-8}\, Nm^{-2}$ |
