Question

in the wave diagram, the horizontal distance from crest to crest (a, b, c and d) is labeled. which property is being measured?
wavelength
frequency
amplitude
rest position

Explanation:

The wavelength of a wave is defined as the horizontal distance between two consecutive crests (or troughs). In the given wave - diagram, the horizontal distance from crest to crest is being measured, which is the definition of wavelength. Frequency is the number of waves passing a point per unit time, amplitude is the maximum displacement from the rest position, and rest position is the equilibrium position of the wave.

Answer:

Wavelength
