WebThe relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 2. WebThe speed of second sound is close to zero near the lambda point, increasing to approximately 20 m/s around 1.8 K, [11] about ten times slower than normal sound waves. [12] At temperatures below 1 K, the speed of second sound in helium II increases as the temperature decreases. [13]
