Energy, Frequency, Wavelength and the Electromagnetic Spectrum The light from a heated element is made of several different colors all mixed together. A spectroscope separates these colors. Some spectroscopes use a prism to separate the colors and some use a diffraction grating. A diffraction grating...

Wavelengths are typically measured in the following units: Kilometers (km). Meters. Millimeters. Micrometers (μm). Nanometers. Picometers (pm). Femtometers (fm). The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma ...
The presented wavelength conversion scheme based on plasmon-coupled surface states can be used for optical wavelength conversion to different parts of the electromagnetic spectrum ranging from microwave to far-infrared regimes in both pulsed and continuous wave operation (Supplementary Fig. 13). The wave...
The quantum helped explain why such a body emits radiation mostly in the middle of the electromagnetic spectrum, rather that in the ultraviolet as predicted by classical theory. Planck's explanation posited that light consists of discrete packets of energy called quanta, or photons, and that the...
