Consider electrons of kinetic energy 5.29 eV and 529 keV. For each electron, find the de Broglie wavelength (in nm), particle speed (in m/s), phase velocity (speed, in m/s), and group velocity (speed, in m/s). nm 5.29 eV electron de Broglie wavelength particle speed phase velocity group velocity m/s m/s m/s 529 keV electron nm de Broglie wavelength particle speed phase velocity group velocity m/s m/s m/s
For a free electron with 100 keV kinetic energy, calculate the: a) electron speed b) electron momentum c) de Broglie wavelength of the electron
An electron in a television picture tube has a classical kinetic energy of 78 keV, which is the kinetic energy that Newton would calculate using the measured speed and rest mass of the electron. What is the actual kinetic energy of the electron; that is, what is the value found using the relativistic result for the kinetic energy? (Give your answer in units of keV)
An electron with a kinetic energy of 2.00 keV (1 eV = 1.602 × 10-19 J) (See the figure above.) is fired horizontally across a horizontally oriented charged conducting plate with a surface charge density of σ = +4.00×10-6 C/m2. Taking the positive direction to be upward (away from the plate), what is the vertical deflection of the electron after it has traveled a horizontal distance of 4.00 cm? Show all work. Include your explanation and show your calculation in...
