A harmonic electromagnetic plane wave with a wavelength of 0.12 m travels in vacuum in the positive z-direction. It oscillates along the x-axis such that at t = 0 and z = 0, the E-field has a maximum value of E(0, 0) = +6.0 V/m.

(a) Write an expression for vector E(z, t).

(b) Write an expression for the magnetic field.

(c) Write an expression for the vector momentum density of the wave.
