What is the formula to calculate wave speed?

• A. Speed = wavelength / frequency
• B. Speed = frequency × amplitude
• C. Speed = frequency × wavelength
• D. Speed = amplitude / wavelength

Answer: (C)

The correct formula for calculating wave speed is given by the relationship between frequency and wavelength. Wave speed is determined by multiplying the frequency of the wave by its wavelength. This indicates how fast the wave propagates through a medium. Frequency is the number of wave cycles that occur in one second, while wavelength is the distance between consecutive points of the same phase on the wave (for example, from crest to crest). By multiplying these two quantities, you obtain the speed at which the wave travels, which is expressed as distance per time. The combination of frequency and wavelength captures the essential characteristics of wave motion, as a higher frequency typically leads to shorter wavelengths, while a lower frequency corresponds to longer wavelengths, maintaining the constant speed of the wave in a given medium. This relationship is fundamental in the study of waves and helps in understanding various phenomena in physics, such as sound and light propagation.
