An electrically maintained tuning fork oscillates with a constant frequency and a constant amplitude. When the temperature of the surrounding air rises while the pressure is kept constant, the produced sound will exhibit

Step-by-step solution

The frequency of the sound produced is determined by the source, which is the electrically maintained tuning fork. Since it oscillates with a constant frequency, the frequency f and time period T of the produced sound remain constant. The velocity of sound in a gas is given by v = RT M . As the temperature T of the surrounding air increases, the velocity of sound v increases. The wavelength of the sound wave is given by = v f . Since v increases and f is constant, the wavelength also increases. Therefore, the sound
