Question

An EM wave propagating in x-direction has a wavelength of 8 mm. The electric field vibrating y-direction has maximum magnitude of 60 Vm⁻¹. Choose the correct equations for electric and magnetic fields if the EM wave is propagating in vacuum:

Accepted Answer

(B) E y = 60 sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] j V m⁻¹ B z = 2 × 10⁻⁷ sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] k T

Answer

(A) E y = 60 sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] j V m⁻¹ B z = 2 sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] k T

Answer

(C) E y = 2 × 10⁻⁷ sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] j V m⁻¹ B z = 60 sin [ (π)/4 × 10³(x - 3 × 10⁸t) ] k T

Answer

(D) E y = 2 × 10⁻⁷ sin [ (π)/4 × 10⁴(x - 4 × 10⁸t) ] j V m⁻¹ B z = 60 sin [ (π)/4 × 10⁴(x - 4 × 10⁸t) ] k T
