PHYS 165 MODULE 10 EXAM QUESTIONS AND
ANSWERS 2026 FULL PRACTICE TEST
◉ Atomic Spectra. Answer: the fingerprints of the atomic world.
◉ Emission spectrums. Answer: created by the exciting of a pure
sample of a material. Usually by passing current through the sample
and it emits light as a result.
the light is sent through a diffraction grating, only certain
frequencies of light come through.
◉ ground state. Answer: the location of the electrons when they
have the least amount of energy
◉ Compton Scattering Effect. Answer: interaction between x-rays
and matter characterized by an incident x-ray photon interacting
with a loosely bound outer-shell electron, resulting in removal of the
electron from the shell, which then proceeds in a different direction
as a scattered photon
◉ Wave-Particle Duality. Answer: the concept that all matter and
energy exhibit both wave-like and particle-like properties
, ◉ Broglie Wavelength equation. Answer: lambda = h/p
lambda = h/mv
◉ Wave-Particle duality factors. Answer: if photon energy less than
visible then particle like behavior
if photon energy more than visible light then wave like behavior
if wavelength less than 1x10^-8 then particle behavior
if wavelength more than 1x10^-6 then wave behavior
if wavelength and/or photon energy at visible spectrum then both
are in effect.
◉ Heinsenberg Uncertainty Principle. Answer: the more accurate
the position of an object , the less accurate the momentum.
Delta x * Delta p greater or equal than h / 4 pi
◉ wave function. Answer: shows the location of an object in terms of
probability.
