What is defined as the maximum displacement of a wave from its equilibrium position?

Wavelength
Amplitude
Frequency
Phase

The correct answer is: Amplitude

The maximum displacement of a wave from its equilibrium position is known as amplitude. In the context of wave physics, amplitude refers to how far the wave oscillates from its rest position, which directly impacts the energy carried by the wave. A larger amplitude means that the wave carries more energy, while a smaller amplitude indicates less energy. Wavelength pertains to the distance between successive crests or troughs of a wave, frequency relates to the number of oscillations or cycles that occur per second, and phase describes the position of a point within a wave cycle relative to a reference point. Each of these concepts plays a crucial role in wave behavior but does not define the maximum displacement from equilibrium as specifically as amplitude does.
