what is frequency

what is amplitude
what is equilibrium
what is wavelength

Frequency is the number of cycles of a periodic wave that occur in a unit of time, usually measured in Hertz (Hz).

Amplitude is the maximum displacement or distance of a wave from its equilibrium position. It represents the intensity or strength of the wave.

Equilibrium refers to the resting or neutral position of a wave or system. It is the state of balance where the forces or factors acting on the system are equal or canceled out.

Wavelength is the distance between two corresponding points on a wave, such as the distance between two consecutive crests or troughs. It is usually denoted by the symbol lambda (λ) and is measured in meters (m) or any other unit of length.

use the "diagram" to answer the question

0.5=highest point of wave
2 cm=lowest point of wave

what does the value 0.5 represent for the wave?
frequency frequency amplitude amplitude equilibrium equilibrium wavelength

Based on the given "diagram", the value 0.5 represents the amplitude of the wave.
