WebCalculate the speed of sound on a day when a 1500 Hz frequency has a wavelength of 0.221 m. (a) What is the speed of sound in a medium where a 100-kHz frequency produces a 5.96-cm wavelength? (b) Which substance in Table 1 is this likely to be? Show that the speed of sound in 20.0ºC air is 343 m/s, as claimed in the text. WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as. v w = f λ. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8.

Webspeed of sound (m/s) = 331.5 + 0.60 T (°C) For example, the speed of sound in air is 386 m/s at 100 °C. The sound of speed in air is increased by 0.60 m/s for each increase of degree in air temperature. The speed of sound is faster at higher temperatures because molecules collide more often.
