This comes from the fact that wavelength and frequency are inversely related. \[\nu \] = 1200 Hz, v = 360 m/s, \[\lambda \]=? This makes sense, because if the wave oscillates a lot (its frequency is high), there have to be more peaks per a given time period, and thus the time between the waves must be shorter. 2.99792 x 10^8 m/s. In the electromagnetic spectrum there are many different types of waves with varying frequencies and wavelengths.
