A tuning fork vibrating at 600 Hz is immersed in a tank of water, and the resulting sound waves in the water are found to have a wavelength of 8.2 ft. What is the velocity of sound in the water?

Hmmm, I keep saying this.
Frequency times wavelength = velocity.
Plug in, multiply.
Your answer will be in feet/s. Convert if you need to.

it fairly is a case of vibration of air column in closed tubes. here one metre tall Vertical tube is initially crammed with water.Water is slowly drained from the backside,then an air column is formed interior the tube The length of the air column is measured from the open end of the tube to the water point.because of the fact the water drain out the dimensions of the air column will improve.At a particular length ,the air column resonates , vibrates with the comparable frequency as that of the tuning fork.it rather is the essential mode of vibration.as a result the dimensions of the air column(measured from the right of the tube to the water point) vibrated would be a million/4th of the wave-length.because of the fact the dimensions the dimensions of the air column will improve lower back resonance exceeded off whilst the dimensions of the air column reaches 3/4th of the wave-length,5/4th of the wave length......etc. here what's occurred on your calculation is which you have measured the dimensions of the air column from the backside,fairly there is not any air column there.

Wavelength = v/f. so v = f*L 600*8.2 = 4920 ft/sec
