QUANTUM PHYSICS QUESTIONS ANDANSWERS WITH SOLUTIONS 2024
Photon - ANSWER A discrete unit or package of light energy
Photoelectric Effect - ANSWER The emission of electrons from a metal when electromagnetic radiation of
high enough frequency falls on the surface
Threshold Frequency (f₀) - ANSWER The minimum frequency of light needed to eject electrons from a
metal surface
Work Function (Φ) - ANSWER The minimum energy needed to eject electrons from the surface of a
metal
Millikan's Stopping Potential Experiment - ANSWER An experiment utilizing reverse voltage raised to
such a level (stopping potential Vs) that it stops all emitted photoelectrons (NOTE: This experiment is
used to test the Einstein model of the explaining the photoelectric effect.)
de Broglie Hypothesis - ANSWER All particles can behave like waves whose wavelength is given by λ = h/p
where h is Planck's constant and p is the momentum of the particle.
Matter Waves - ANSWER All moving particles have a "matter wave" associated with them whose
wavelength is the de Broglie wavelength.
Wave-Particle Duality - ANSWER Both matter and radiation have a dual nature. They exhibit both particle
and wave properties.
Davisson-Germer Experiment - ANSWER An experiment showing that electrons are scattered off crystals
of nickel and interfere with each other - also know as "electron diffraction" (NOTE: This experiment is
evidence for the existence of matter waves.)
Electron in a Box Model - ANSWER A model of the atom useful for explaining the origin of atomic energy
levels: The model assumes that, if an electron is confined to move in one dimension by a box, the de
Broglie waves associated with the electron will be standing waves of wavelength 2L/n where L is the
