How is wave speed calculated?

Wave speed is calculated using the relationship between frequency and wavelength. The formula states that wave speed is equal to the frequency of the wave multiplied by its wavelength. This relationship is fundamental in understanding wave mechanics, as it shows how the speed at which a wave travels is directly influenced by both its frequency (the number of cycles that pass a point per second) and its wavelength (the distance between successive crests or troughs of the wave).

When you increase the frequency while keeping the wavelength constant, the wave speed increases, and vice versa. This principle is applicable to various types of waves, including sound waves in air and electromagnetic waves. Therefore, the correct calculation of wave speed is indeed given by multiplying the frequency by the wavelength, which clearly defines the relationship between these key aspects of wave behavior.
