Question

What are wavelength and amplitude?

Answer 1

Wavelength-the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Amplitude-the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Answer 2

wavelength- the distance between two successive compression and rarefractions is called wavelength.

amplitude- the maximum displacement of a vibrating body from its rest position to it's mean position.
