Vu,
There is a very simple relationship between wavelength and frequency: λ=v/f. In this case you're referring to the frequency of a tuning fork, so v refers to the speed of sound, or in words:
(wavelength) = (speed of sound)/(frequency)
The speed of sound v = 343 m/s and Hz = 1/s so
wavelength = (343 m/s) / (512 1/s) = 0.67 m

Hi Vu, Use the general equation: Wave speed (m s^-1) = wavelength (m) * frequency (waves s^-1, or just s^-1) . You can see that the units combine appropriately -- figuring problems out this way is called "dimensional analysis". Wave speed = speed of sound in air, look it up. -- Cheers, -- Mr. d.06/03/20
