If the intensity of an electromagnetic wave is 80 MW/m^2, what is the amplitude of the magnetic field of this wave? (c = 3.0 x 10^8 m/s, permeability of free space ''miu subzero''= 4π × 10^-7 T ∙ m/A, permittivity of free space ''E subzero'' = 8.85 × 10^-12 C^2/N ∙ m^2)
80MW/m^2= 80,000,000 W/m^2
(80x10^6)(4pi x10^-7)/ 8.85x10^-12 = 1.132x10^13 ?
80MW/m^2= 80,000,000 W/m^2
(80x10^6)(4pi x10^-7)/ 8.85x10^-12 = 1.132x10^13 ?
