Compute all parts of given problem:
Problem: An electromagnetic wave with frequency 65.0Hztravels in an insulating magnetic material that has dielectric constant 3.64 and relative permeability 5.18 at this frequency. The electric field has amplitude 7.20×103 V/m.
Part I: What is the speed of propagation of the wave?
Part II: What is the wavelength of the wave?
Part III: What is the amplitude of the magnetic field?
Please show all steps to calculate the speed of propagation of the wave.
