Electromagnetic radiation are represented in waves. Each type of wave has a certain shape and length. The distance between two peaks in a wave is called the wavelength. This value is equal to the speed of light divided by the frequency. Wavelength = c/f Wavelength = 3x10^8 / <span>5.42x10^15 </span><span>Wavelength = 5.54 x 10^-8 m = 55.35 nm</span>
