Figure 34.3 shows a plane electromagnetic sinusoidal wave propagating in the x direction. Suppose that the wavelength is 50.0 m, and the electric field vibrates in the xy plane with amplitude of 22.0 V/m. Calculate
(a) The frequency of the wave and
(b) The magnitude and direction of B when the electric field has its maximum value in the negative y direction.
(c) Write an expression for B with the correct unit vector, with numerical values for Bmax, k, and %, and with its magnitude in the form B = B max cos (kx – wt)
