Answers (100% Expert Answers) A+
What is paramagnetism? [ Ans: ] When you have at least one unpaired
electron.(electrons in it point towards direction with magnet)
What is defraction? [ Ans: ] the process by which a beam or a wave bends
around an object.
What is interference? [ Ans: ] the combination of two or more waves that
results in a single wave
What is constructive interference? [ Ans: ] Where two waves arrive in step
reinforcing one another (increasing the amplitude)
What is destructive interference? [ Ans: ] Where two waves arrive out of

step cancelling one another out
What is diamagnetism? [ Ans: ] when all electrons are paired.
What was the double slit experiment? [ Ans: ] An experiment that studied
the interference patterns of two waves
What was the result of the double slit experiment? [ Ans: ] There was an
interference pattern of light and dark bands due to both constructive and
destructive interference.
What is a photon? [ Ans: ] a particle of light, explaining the photoelectric
effect
What is the photoelectric effect? [ Ans: ] The emission of electrons from a
metal when light of a specific energy shines on the metal
What is v threshold? [ Ans: ] The frequency of light required to transfer
its energy to an electron
, 2
What happens to the photon after it transfers its energy to an electron? [
Ans: ] The photon is destroyed
What is binding energy, or theta? What does it give us? [ Ans: ] This is the
amount of energy that an electron is bound to a metal with. It depends on
the identity of the metal. This gives us the work function
What does the color of light tell us? [ Ans: ] wavelength and frequency
What does the intensity of the light tell us? [ Ans: ] amplitude
What is atomic spectroscopy? [ Ans: ] The study of how light interacts
with matter
What is the bohr model of the atom? [ Ans: ] electrons orbit the nucleus
only at specific distances
What is coulomb's law? [ Ans: ] E= 1/(4πε₀) x (q₂q₁)/r
© 2026
Is energy conserved in the photoelectric effect? [ Ans: ] Yes
What is psi squared? (looks like a trident) [ Ans: ] The probability. It is
equiavalent to psi1+ psi 2 squared
What is Shrodingers equation? [ Ans: ] H psi= E psi
What is wrong with the following equation? Ef- Ei= -2.18E-18J (1/nf^2-
1/ni^2) [ Ans: ] This can only be used to calculate the energy change of
hydrogen atoms. To calculate the energy of other atoms, you can to
multiple the right side of the equation by the number of protons squared.
Can you have two atoms with the quantum number Ms= +1/2? [ Ans: ] no
What is Heisenberg's uncertainty principle? [ Ans: ] ∆x m∆v>=h/4π
What is the principle quantum number? [ Ans: ] n= it indicates the orbital
size and energy
