If a tuning fork puts out a tone at 440 Hz, what is its wavelength in air at 25 degrees?

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

To find the wavelength of a sound wave, we can use the formula:

wavelength = speed of sound / frequency

The speed of sound in air at 25 degrees Celsius is approximately 343 meters per second. We convert this to meters per second because the formula requires the speed to be in meters per second and the frequency to be in hertz.

Now, we can substitute the values into the formula:

wavelength = 343 (m/s) / 440 (Hz)

By dividing 343 by 440, we get the wavelength of the sound wave produced by the tuning fork at 440 Hz in air at 25 degrees Celsius. Therefore, the wavelength is approximately 0.7795 meters, or about 77.95 centimeters.
