The wavelength and frequency are related by the speed of electromagnetic radiation, c= 3.00 x 108m/s c = λν where λ≡ wavelength (m) and ν≡ frequency (s-1) The energy, E, associated with a particular frequency can be calculated using Planck’s constant (h = 6.63 x 10-34J•s) E = h ν

Sunlight (white light) contains all wavelengths of visible light. In other words, it gives a continuous spectrum, observed as a rainbow. Incandescent solids, liquids, and high pressure gases also give continuous spectra. When an electric current is passed through a gas in a
