When the frequency of a wave increases, the wavelength decreases, and vice versa. The relationship between frequency (f) and wavelength (λ) is given by the wave equation:
v = f * λ
where v represents the wave velocity. As the frequency increases, the wavelength decreases, assuming the velocity remains constant. This means that as waves become more frequent (higher frequency), they become compressed, and the distance between successive wave crests or troughs decreases.
Conversely, when the frequency decreases, the wavelength increases. Waves with lower frequencies are stretched out, and the distance between wave crests or troughs becomes longer.
Regarding amplitude, it does not directly depend on the frequency or wavelength of a wave. Amplitude refers to the maximum displacement or height of the wave from its equilibrium position. It represents the intensity or strength of the wave, but it is unrelated to its frequency or wavelength. Changing the frequency or wavelength of a wave does not affect its amplitude unless there are other factors involved, such as damping or resonance.
