From a ceiling, a rope with the mass m and length L hangs. Demonstrate that v =√gy is the wave speed on the rope at a distance of y above the lower end.
The amount of space a wave covers in a certain amount of time, such as the number of meters it covers in a second, is known as its wave speed. Speed = Wavelength x Frequency is an equation that describes how wave speed relates to wave wavelength and wave frequency. When the wavelength and frequency are known, this equation can be used to determine the wave speed. Wave frequency (f) is recorded in hertz, while wave speed (v) is measured in meters per second (m/s) (Hz)
Although technically, velocity means both speed and direction, wave velocity is most often used to refer to speed. A wave's velocity is independent of its intensity and equal to the product of its wavelength and frequency (number of vibrations per second).
