A sound wave is traveling in seawater, where the adiabatic bulk modulus and density are $2.31 \times 10^{9} \mathrm{~Pa}$ and $1025 \mathrm{~kg} / \mathrm{m}^{3}$, respectively. The wavelength of the sound is $3.35 \mathrm{~m}$. A tuning fork is struck under water and vibrates at $440.0 \mathrm{~Hz}$. What would be the beat frequency heard by an underwater swimmer?

Step 1
First, we need to find the speed of sound in seawater. We can use the formula: $$v = \sqrt{\frac{B}{\rho}}$$ where $v$ is the speed of sound, $B$ is the adiabatic bulk modulus, and $\rho$ is the density of the medium. Show more…

A tuning fork is struck under water and vibrates at 440.0 Hz. What would be the beat frequency heard by an underwater swimmer?
A tuning fork vibrating at 300 Hz is placed in a tank of water. What is the wavelength of the sound waves produced in the air above the tank by the vibrations of the water surface if the velocity of sound in air is 1125 ft/s? None of the choices 2.15 ft 5.30 ft 3.75 ft 0.27 ft
