A guitar string sends out waves that hit your ear. in 2 seconds, 76 wave cycles hit your ear

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?

Could someone me find the answer to this problem.
