A Totally Absorbing Surface Having an Area of 7

question 30

Short Answer

A totally absorbing surface having an area of 7.7 cm² faces a small source of sinusoidal electromagnetic radiation that is 2.4 m away.At the surface,the electric field amplitude of the radiation is 84 V/m.(c = 3.00 × 10⁸ m/s,μ₀ = 4π × 10^-7 T ∙ m/A,ε₀ = 8.85 × 10^-12 C²/N ∙ m²)
(a)What is the radiation pressure exerted on the surface?
(b)What is the total power output of the source,if it is assumed to radiate uniformly in all directions?
