1. What is a wave? an oscillation or periodic movement that can transport energy from
one point in space to another
2. what is the constant (c)? 2.998 x 10^8 m/s
3. what is (λ)? wavelength
the distance between two consecutive peaks/troughs (in m)
4. what is (v)? frequency
the # of wave cycles that pass a specific point in space in a specified
amount of time (in hertz (Hz) or 1/s)
5. what is the amplitude? the magnitude of the wave's displacement, which is 1/2 the height
between peaks/troughs
6. how are wavelengths and they are inversely proportional
frequency related?
7. what is the theory of elec- developed by James Maxwell
tromagnetic radiation?
showed that light was the visible part of a vast spectrum of electro-
magnetic waves
8. what is a blackbody? an object that absorbs light of any frequency, and reflects no light
(black)
9. who developed the equa- Max Planck
tion that describes black-
body radiation? E = nhv
10. what is Planck's constant 6.626 x 10^-34 Js
(h)?

11. what is wave theory? a wave's energy depends on its intensity, which depends on its am-
plitude
12. who discovered photons? Albert Einstein
13. what is the equation to E = hv
find the energy of a pho-
ton of light (E)? or
E = hc/λ
14. what is wave-particle du- The concept that every elementary particle or quantic entity exhibits
ality? the properties of not only particles, but also waves
15. which observations -optical phenomena such as reflection/refraction
and/or theories support -light passing through narrow, closely spaced slits produces interfer-
the wave nature of light? ence patterns
-James Clerk Maxwell's theory of electromagnetic radiation
16. which observations -Newton's law of motion (light was streams of extremely tiny particles
and/or theories support traveling at high speeds according to his laws of motion)
the particle nature of -photoelectric effect
light? -blackbody radiation
17. what are the main fea- 1. the energies of electrons (energy levels) in an atom are quantized
tures from Bohr's mod- 2. an electron's energy increases with increasing distance from the
el of the hydrogen atom nucleus
that apply to all models 3. the discrete energies of light emitted by elements in an excited
used to describe the dis- state result from quantized electronic energies
tribution of electrons in
an atom?
