Auger Electron Spectroscopy

Auger Electron Spectroscopy. (AES). Principle of AES. A fine focused electron beam bombards the sample and ejects an electron of the inner shell of the atom. This vacancy must be refilled by an electron from a higher energy level.

Light is a wave or electric and magnetic energy

Light is a wave or electric and magnetic energy. The speed of light is 186,000 mi/s = 300,000 km/s. Energy = hf = hc / l f = frequency h = Planck's constant l = wavelength. c = f x l. c = speed of light. Highest energy ( E ) Highest frequency ( f ) Shortest Wavelength ( l ).

Types of Spectra

Types of Spectra. Spectra. Most of you have seen light passed through a prism and separated into a rainbow of colors. Today you will use a different device to get a separation of colors. This device is known as a diffraction grating .
