Question

A loudspeaker produces sound waves that change in wavelength from 1.0 m to 1.5 m. If the wave speed is constant, how did the vibration of the loudspeaker change?
A)The vibration frequency increased. As wavelength decreases, its frequency decreases.
B)The vibration frequency increased. As wavelength increases, its frequency increases.
C)The vibration frequency decreased. As wavelength decreases, its frequency decreases.
D)The vibration frequency decreased. As wavelength increases, its frequency decreases.
