A parabolic reflector focuses electromagnetic waves into a beam as shown in the figure. The electromagnetic radiation is pulsed, with a pulse frequency of 16.0 GHz, and the duration of each pulse is t = 1.00 ns. The face of the reflector has a radius of 5.00 cm, and the average power during each pulse is 20.0 kW. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) What is the wavelength (in cm) of these electromagnetic waves? cm (b) What is the total energy (in µJ) contained in each pulse? (c) Compute the average energy density (in mJ/m³) inside each pulse. mJ/m³ (d) Determine the amplitude of the electric field (in kV/m) and magnetic field (in µT) in these electromagnetic waves.
