We've got a measure of distance from the wavelength of the wave, and we've got a measure of time from the frequency. Wavelength is meters per cycle. Frequency is cycles per second. So, multiplying the two gives us meters per second.
Simply wavelength. The wavelength is the length of the ultraviolet or infrared waves from one point (say, the crest) on one wave to the same point on the next.
