Q.What do you mean by the terms wavelength, frequency and amplitude of a wave motion?

Wavelength is the spatial repeat length of the wave, frequency is how many waves pass per second, and amplitude is the maximum displacement of the vibrating particles.

Wavelength (λ): The wavelength of a periodic wave is the minimum distance between two points on the wave that are in exactly the same state of vibration (same phase) — for example, the distance from one crest to the next crest, or from one compression to the next compression. It is measured in metres.

Frequency (f or ν): The frequency of a wave is the number of complete oscillations (or complete waves) that occur, or that pass a given point, in one second. It is measured in hertz (Hz), where 1 Hz = 1 oscillation per second. Frequency is related to the time period T (time for one complete oscillation) by f = 1/T.
