a) An electromagnetic wave is travel in free space in the x-axis direction as shown in Figure 5 below. Given the frequency of the wave is 50.0MHz. i. Calculate the wavelength and period of the wave. [2 marks] ii. Calculate the maximum value of the magnetic field if given at certain point and time the electric field has its maximum value of 800N/C. [2 marks] iii. Write the travelling wave equation for the electric and magnetic field components for this wave. [4 marks] rigures
