Energy of motion
Kinetic energy (Ek)
(λ; lambda)—the
distance between identical points on
successive waves.
Wavelength
Electromagnetic radiation emitted when a solid is heated
blackbody radiation
E=hv
Energy
Energy possessed by an object by virtue of
its position
Potential energy
(ν; nu)—the number of
waves that pass through a particular
point in 1 second
Frequency
the smallest quantity of energy that can
be emitted (or absorbed).
a quantum of energy
Ek=(1/2)mu2
Kinetic energy
Energy associated with the random
motion of atoms and molecules
Thermal energy

energy stored within the structural
units of chemical substances

surface of a metal exposed to light of
a certain minimum frequency
threshold frequency
1/λ=R∞ [(1/n12)-(1/n22)]
Rydberg
potential energy that results from
the interaction of charged particles
Electrostatic energy
states that it is impossible
