Explanation:
Detailed explanation-1: -Harmonic waves have the form, y=Acos(2x−2tT+). y = A cos Here A is the amplitude, is the wavelength, T is the period, and is the phase.
Detailed explanation-2: - represents the frequency of a sine wave when we write it this way: sin(t). If =1 the sin completes one cycle in 2 seconds. If =2 the sin completes one cycle sooner, every 1 second.
Detailed explanation-3: -A sine wave or sinusoidal wave is the most natural representation of how many things in nature change state. A sine wave shows how the amplitude of a variable changes with time. The variable could be audible sound for example.
