In vacuum,the components of an EM wave are E_y = 50( V/m )cos[(5.00 m^-1)x + $\omega$t], E_x = 0, and E_z = 0.What is the wavelength of the wave? A) 5.00 m B) 0.200 m C) 1.26 m D) 2.52 m E) 0.796 m

Question

Quizplus · Accepted Answer

The wavelength of EM wave is given by the equation:

λ = 2π/k

where k is the wave vector.

For this EM wave, we are given that:

k = (5.00 m^-1)

Therefore,

λ = 2π/ (5.00 m^-1) = 1.26 m

So, the wavelength of the wave is 1.26 m.

Therefore, the correct choice is (C).

In Vacuum,the Components of an EM Wave Are Ey = ω\omegaω
