A microphone is undergoing simple harmonic motion (SHM) above a 440-Hz sound source as shown in the figure. The period of the microphone's SHM is 2.0 s and there is a difference of 2.1 Hz between the highest and lowest recorded frequencies. Ignoring any reflections of sound in the room and using the velocity of sound in air at room temperature, determine the amplitude of the simple harmonic motion.
The spring of the pressure gauge has a force constant of1000 n/m and the piston has a diameter of 2.00 cm as the gauge is lowered into water, what change in depth causes piston to move in by 0.50 cm.
Suppose that the sound level of a conversation is initially at an angry 70 dB and then drops to a soothing 50 dB. Assuming that the frequency of the sound is 500 Hz, determine the (c) initial and (d) final sound wave amplitudes.
