Question

define wavelength - the distance between consecutive corresponding points on a frequency - the number of times a repeating event occurs per unit of time amplitude - energy -

Explanation:

Wavelength is the spatial period of a wave. Frequency is how often a wave - like event repeats per unit time. Amplitude is the maximum displacement from the equilibrium position of a wave. Energy in the context of waves is related to the amplitude and frequency, representing the capacity to do work. For a wave, energy is proportional to the square of the amplitude and also related to the frequency through the Planck - Einstein relation ($E = h
u$ for quantum - mechanical waves).

Answer:

Amplitude - The maximum displacement from the equilibrium position of a wave.
Energy - In the context of waves, related to amplitude and frequency; for quantum - mechanical waves, $E = h
u$ (where $E$ is energy, $h$ is Planck's constant, and $
u$ is frequency), and also proportional to the square of the amplitude for classical waves.
