Asked by Amber

If a tuning fork puts out a tone at 440 Hz, what is its wavelength in air at 25 degrees?
Answered by Ariel
in my equation A will be wavelength since I don't have a lamda key

v = fA

To find the velocity of the wave in air at 25 degrees Celsius, first convert to Kelvins 273 + 25 = 298K

Use this equation to determine velocity of air at a certain temperature

v = 331m/s x sqrt(298K/273K) =
345.8237m/s

Then just plug into your equation
v = fA
A = v/f
A = (345.8237m/s)/(440Hz)
A = .79m
