The speed of sound increases by about 0.6 m/s for each degree Celsius when the air temperature rises. For a given sound, as the temperature increases, what happens to the following?
a. the frequency
b. the wavelength
a. The frequency of the sound remains the same. It is determined by the source of the sound, not the medium it travels through.
b. The wavelength of the sound increases. This is because the speed of sound is directly proportional to the wavelength. As the speed of sound increases with temperature, the wavelength also increases.
