Question

Which frequency or frequencies w>0 will maximize the amplitude dain in the second order equation

Answer 1

Changing frequency does not change amplitude.

amplitude: distance between the resting position and the maximum displacement of the wave

amplitude: distance between the resting position and the maximum displacement of the wavefrequency: number of waves passing by a specific point per secondperiod: time it takes for one wave cycle to completeIn addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ is the distance between adjacent identical parts of a wave, parallel to the direction of propagation. The wave velocity vw is the speed at which the disturbance moves.
