A tuning fork emits sound waves into the air. If the temperature of the air rises, which of the following parameters will change?

Step-by-step solution

The frequency of a sound wave depends only on the source (the tuning fork) and remains constant regardless of the temperature of the medium. Since the frequency f is constant, the time period T = 1 f also remains constant. The speed of sound in a gas is directly proportional to the square root of its absolute temperature, v T . As the temperature of the air rises, the speed of sound v increases. From the wave relation v = f , since the speed v increases and the frequency f remains constant, the wavelength must incr
