you have to divide the speed of light by the wavelength to get the frequency.

An electronic instrument, like an oscilloscope?
10 to the negative 3 in what units? Angstroms? Millimeters? Microns?

λ = wavelength of a sound wave or electromagnetic wave
vw = the speed of propagation of the wave
f = frequency of the wave in 1/s = Hz.

wavelength * frequency = speed
electromagnetic waves have a constant speed. ( the speed of light)

basic equation is
c = lambda * nu
c is the speed of light
lambda is wavelength (which units are you using?)
nu is the frequency
divide c (3E8 m/s roughly) by your wavelength (in meters), and you'll get the frequency, in Hertz.
