A plane electromagnetic wave of wave intensity 6 W/m2 strikes a small mirror area 40 cm2 , held perpendicular to the approaching wave. The momentum transferred by the wave to the mirror each second will be?
Added by Shirlin S.
Step 1
Given intensity \(I = 6 \, \text{W/m}^2\) and area \(A = 40 \, \text{cm}^2 = 40 \times 10^{-4} \, \text{m}^2\). Therefore, \(P = 6 \times 40 \times 10^{-4} = 0.24 \, \text{W}\). Show more…
