Draw on the graph the line that is your estimate of the best straight line fit to the data points. From this experiment, determine a value of Planck's constant h in units of electron volt-seconds and determine the threshold frequency and work function for the metal.

Obviously, for an electron to be emitted with any kinetic energy requires h > w and the threshold (“minimum”) energy required to eject an electron is the electron work function for the electron. EXERCISES: 9. The value of the electron work function for cesium (Cs) is 2.14 eV, where 1 eV (electron volt) has an energy of 1.602 177 x 10–19 J.

The electron-Volt (eV) is a useful unit of energy in particle physics. It is the energy (U=qV) acquired by moving the electron charge (q=1.6x10-19 Coulombs) through an electric potential of 1 Volt. Therefore 1 eV = 1.6x10-19 Joules. Likewise eV/c, where c is the speed of light in vacuum, is a unit of momentum and eV/c2 is a unit of mass.

Frequency and wavelength are inversely related: higher frequency means shorter wavelength; lower frequency means longer wavelength. 2. Eye and brain associate color with different wavelengths of light. 3. a) The 2.0 m wavelength wave has higher frequency. b) Period is the time required for a wave to pass a point (it's the reciprocal of frequency).

b) To convert between electron volts and joules, just multiply by e (1.6 x 10-19). This actually makes a lot of sense. 2eV=2∙e∙V=2 1.6 x 10 -19 =3.2 x 10 -19 J . Because we will often be dealing with small amounts of energy in this unit, using the electron volt will many times be easier. Reading 2: Black Body Radiation. Problems with Wave ...
