If the kinetic energy of the electron is determined based on that relationship, then the energy levels of the hydrogen atom are also determined. In classical quantum theory, there is a formula called the Rydberg
The de Broglie wavelength of the photon is 442 nm. This wavelength is in the blue-violet part of the visible light spectrum. 2) The de Broglie wavelength of a certain electron is . The mass of an electron is me= 9.109 x 10(-31)kg. What is the magnitude of the velocity of this el...
is the wavelength of the incident photon, and ? is the work function of the metal surface. What is the kinetic energy formula? In classical mechanics, kinetic energy (KE) isequal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object wit...
