amplitude - CORRECT ANSWER: magnitude of the waves displacement s


atoms vibrate at - CORRECT ANSWER: increasing frequencies (decreasing wavelengths) as the
temperatures increase


binding energy - CORRECT ANSWER: each metal has a particular electrostatic attraction for its
electrons that must be overcome before an electron can be emitted from its surface



black body - CORRECT ANSWER: a perfect emitter and absorber of all wavelengths of
radiation



Bohr's model of hydrogen - CORRECT ANSWER: E(energy value)=-Ry/n^2 (Ry=constant,
n=quantum number)

-energies of electrons described by quantum numbers -> discrete numbers having a specific
value

-lines of spectra result from quantized by electronic charges



bright regions of a wave - CORRECT ANSWER: correspond to regions where two peaks for the
two waves of their two troughs happen to coincide

-constructive interference



constructive interference - CORRECT ANSWER: The interference that occurs when two waves
combine to make a wave with a larger amplitude
