The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
That also depends on the speed of the wave. Use the formula speed = wavelength x frequency, or wavelength = speed / frequency. In the case of an electromagnetic wave in a vacuum, use 300,000,000 m/s for the speed.
The product of (wavelength) x (frequency) of any wave phenomenon is alwaysthe same number ... the speed of the wave. So if wavelength changes, thenfrequency must change by exactly the same factor in the opposite direction,in order for their product to remain constant.
You know its speed in vacuum, and frequency = (speed) / (wavelength) .

Just divide the speed of light (300,000,000 meters/second) by the wavelength.

You need to divide the speed of light (in m/s) by the frequency (in Hz, which is equal to 1/s) to get the wavelength (in meters).
Wave frequency can be calculated by dividing the speed of the wave (if we're talking about electromagnetic waves in vacuum, that would be the speed of light, c) by wavelength.

The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
