Answer
The wavelength of the sound increases, and the frequency decreases.
Work Step by Step
Moving a band closer to the end of the tine increases the tine’s moment of inertia, making it more difficult to oscillate. This reduces the frequency at which the tines oscillate, which reduces the frequency of the produced sound wave.
The product of wavelength and frequency is the speed of sound in air, so as the frequency decreases, the wavelength increases.
