Wavelength What is the formula for calculating Wavelength? Asked by BookRagsHelper 13 years ago 11/9/2012 1:34 AM Last updated by anonymous 13 years ago 11/15/2012 12:47 AM
You take the speed (C) and divide it by the frequency (f) to get the wavelength (λ). Using the value 3.00 × 108 m/sec will calculate wavelengths for electromagnetic radiation. For speed of sound calculations, C will be about 343 m/sec.
