The electric field associated with a plane electromagnetic wave is given by

$$E_x = 0, \quad E_y = 0 \quad \hbox{\rm and} \quad E_z = E_0 \sin[k(x - ct)] ,$$

where $E_0 = 2.34 \times 10^{-4}$ V/m and $k = 9.72 \times 10^6$ m^-1.

1.

Write expressions for all three components of the magnetic field associated with the wave.

2.

Find the wavelength of the wave.
