E n 1312 n 2 kJmol. Note that when considering electromagnetic radiation such as light the quantity speed is. For a single electron instead of per mole the formula in eV electron volts is also widely used.
The frequency is of quantum mechanical nature.
Frequency of revolution is 655 1015 81. Also calculate the wavelength of a free electron with a kinetic energy of 2 eV. E n 136 n. Frequency of the revolution is 655 1015 n3z2.
