Modern physics
Blackbody - correct answer ✔In object that absorbs 100% of the radiation
that hits it. Therefore it reflects no radiation and appears perfectly black
(absence of light)


Blackbody radiation - correct answer ✔When I blackbody emits specific
amounts of energy thought to be produced by standing waves


What does classical physics tell us - correct answer ✔The amount of
radiation the middle of each frequency should be proportional to the number
of waves present


Quantum - correct answer ✔A small bundle of energy that acts like an
individual particle


Electromagnetic energy can only be emitted in - correct answer ✔Quantized
form (A multiple of a certain number)


Photo electric affect - correct answer ✔When light is exposed to the surface
of certain metals, the light energy is absorbed and electrons on the metal are
ejected


What causes the electrons to be ejected - correct answer ✔By packets of
energy in the light


Light is made up of particles called - correct answer ✔Photons

, Wave particle duality - correct answer ✔This experiment help us understand
that light is neither a wave nor a particle


Photo electric affect showed us that - correct answer ✔And increasing
frequency of light used, results in an increase of the energy of electrons or
photons


Special relativity - correct answer ✔Uniform motion is "relative "meaning it all
depends on your frame of reference
-speed of light is the same in every frame despite motion


Mass energy equivalence - correct answer ✔E=mc^2


Universal mass units - correct answer ✔Used in place of a kilogram


What happens when an electron in a higher energy orbit it jumps to a lower
orbit - correct answer ✔An atom emits EM waves (energy)


Ground state - correct answer ✔The lowest possible energy level


Ionization potential - correct answer ✔The minimum energy necessary to
remove or liberate an electron from an atom (decreases the distance from the
nucleus)


Energy levels - correct answer ✔Negatives to indicate that the electron is
bound by the nucleus of the atom (Energy must be put into the atom)


When electrons are supplied with energy from photons - correct answer
✔The electrons jump to higher energy levels
