Electron Volts. In the past, we spoke briefly about electron Volts. We have only used them a handful of times. In this section, however, they will become incredibly useful. What you need to remember is that a) eV are a measure of energy. b) To convert between electron volts and joules, just multiply by e (1.6 x 10-19). This actually makes a lot ...

Frequency is measured in cycles per second (which is called a Hertz), wavelength is measured in meters and energy is measured in electron volts. The strength of an EMF depends on its wavelength and frequency. A greater number of waves with shorter wavelengths create more energy as you move up the spectrum. Electromagnetic Spectrum In My Home

All particles with frequencies greater than about 10 to the 19th power Hertz (or about 50,000 Electron Volts (5 x 104 eV) are called gamma-rays. Theoretically, there is no hard limit to the energy that a gamma-ray can have; where a typical optical PHOTON is about 2-3 eV. Electricity nevertheless.

Since the energy of an electron accelerated in electric field is proportional to the potential difference, it is often measured in eV (electron-Volts) units, i. e. an electron accelerated by 1 V potential difference acquires energy 1 eV; 1 eV=1.602(10-19 J. 10

Franck Hertz Experiment. Purpose: ... (measured in electron volts) necessary to free the electrons from the cathode. The cathode is coated with a material with a relatively low work function. The collector plate, since it is used merely as electron collector, has a somewhat higher work function. The contact potential is the difference between ...

The Franck-Hertz tube is designed to be plano-parallel so that the accelerating fields are nearly uniform. In order for the electron beam to be approximately monoenergetic, the hot cathode sits behind a non-emitting diaphragm held at the same potential.
