Inverse relationship between the Distance from one peak of a wave to the next. Wavelength is measured in units of distance. The wavelengths of visible light correspond to ~400-650 nm. Wavelength is an important way to characterize a wave. For light, the shorter the wavelength, the higher the energy of the light wave. of electromagnetic radiation, λ, (Å) and the Discrete bundle of light energy. Light of a given energy (frequency) cannot be broken up indefinitely. Rather for a given frequency it comes in discrete bundles with energy (h = Planck's constant and ν= frequency): It is often useful to think of light as a bunch of particle photons; whereas, Click on Term to Read More energy, E, (Joules):
Conversion to Ångstroms and electron volts (1 eV = 1.6021 x 10-19 Joule) yields Duane-Hunt equation:
