The speed of sound=343m/Sec
Wavelength= Speed/Frequency=343/340=1.009m
Frequency= 0.5 Hz.
Human beings can hear sound waves in the frequency range of 20 Hz - 20 kHz. So, the required shortest wavelength that human beings can hear is 20 Hz.

For 440 Hz: λ = about 423.37 miles.
Frequency= 0.5 Hz.
Lower frequency equates to a longer wavelength, so the 340 Hz tuning fork would emit a longer wavelength sound.
Human beings can hear sound waves in the frequency range of 20 Hz - 20 kHz. So, the required shortest wavelength that human beings can hear is 20 Hz.

That depends on its speed, and therefore on the medium it happens to be in. -- In normal air at sea level, 30 Hz corresponds to a wavelength of about 37.5 feet. -- In copper, 30 Hz corresponds to a wavelength of about 506 feet. -- In diamond, 30 Hz corresponds to a wavelength of about 1,315 feet. -- In water, 30 Hz corresponds to a wavelength of about 160 feet.
For a wavelengt lambda in air with the speed of sound of c = 340 meters per second the frequency f: f = c / lambda. A wavelength of 5 meters equals a frequency of 68 Hz. A wavelength of 0.2 meters equals a frequency of 1700 Hz. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links and look at "Acoustic waves or sound waves in air".
3.8 mm = 0.0038 meter(340 meters per second) / (0.0038 meter) = 89,474 per second = 89,474 Hz. (rounded)
For any wave, speed = wavelength x frequency. The speed of sound in air is about 331 m/sec., so the wavelength in this case would be 331 / 100 = 3.31 meters; however, the speed of sound depends on temperature. It also has Avery different values in materials other than air.
