1) What is the length of a box in which the minimum energy of an electron is 1.6×10−18 J ? L= ____________nm 2) A proton is confined within an atomic nucleus of diameter 4.3 fm (1fm=10−15m). Estimate the smallest range of speeds −v0<vp<+v0 you might find for a proton in the nucleus. Express your answer with the appropriate units.
Question 3: Quantum (10 pts) The quantum energy levels of an electron in a box of length of Lare given by En = n2h2/8mL2 where n = 1, 2, 3, ..., h is Planck's constant and m is the mass of an electron. What is the smallest value that I can have if an excited electron in the box possibly produces visible light? Give you answer in units of meters or nanometers.
An electron with kinetic energy K is traveling along the x axis, which is along the axis of a cathode-ray tube as shown in the figure below. There is an electric fieldE 10.00x 101 N/C pointed in the ty direction between the deflection plates, which are d 0.0500 m long and are separated by 0.0200 m. 0.0200 mx 1) Determine the minimum initial kinetic energy the electron can have and stll avoid colliding with one of the plates.

The minimum energy needed to eject an electron from an atom is called its ionization energy I. In atomic physics, I is usually measured in electron-Volts (eV), with 1 eV being the energy needed to move a charge of 1 e across an electrostatic potential difference of 1 V, 1 eV = 1.602 x 10-19 CX1V -1.602 x 10-19 J. For the hydrogen atom | = 13.60 eV. If a photon ejects an electron with kinetic energy 5.0 eV from...
