A sound wave has an intensity level of 121.3 dB in air. The density of air at 20.0°C is ρ = 1.20 kg/m3 (see Table 9.1). The speed of sound in air at 20.0°C is v = 343 m/s (see Table 12.1). What is the pressure amplitude of the wave?
The pan flute is a musical instrument consisting of a number of closed-end tubes of different lengths. When the musician blows over the open ends, each tube plays a different note. The longest pipe is 0.33 m long. What is the frequency of the note it plays?
A tuning fork is held over the top of a graduated cylinder that is slowly filled with water. Two resonances are noted as the cylinder is filled. They occur when the water level is 56.5 cm and 17.5 cm below the rim. Note that there is an end correction, meaning that the effective length of the air column is longer than the observed length by a fixed constant amount. If the speed of sound is 343 m/s, find the frequency of the tuning fork.
