|---|---|---|---|---|---|
| electron configurations | explanations of periodic of the arrangement of electrons w/in atoms
🗑
|
||||
| valance electrons | electrons in he outermost shell
🗑
|
||||
| electromagnetic radiation | consists of oscillating perpendicular electric and magnetic fields that travel through space at the same rate
"spd of light"
2.998 x 10^8 m/s
🗑
|
||||
| Spectrum | the distribution of intensities of wavelengths or frequencies of electromagnetic radiation emitted or absorbed by an object.
🗑
|
||||
| wavelength | distance btwn adjacent crests (or troughs) in a wave
🗑
|
||||
| frequency | # of complete waves passing a pt in a given period of time--that is, cycles per second or simply persecond, 1/s
🗑
|
||||
| lower frequency = | longer wavelength
🗑
|
||||
| higher frequency = | shorter wavelength
🗑
|
||||
| per second is equivalent to | hertz (Hz)
🗑
|
||||
| amplitude | height of the crest
🗑
|
||||
| spd of light (c) | 2.998 x 10^8 m/s
🗑
|
||||
| wavelength is measured in... | (m, nm. etc.) unit length
🗑
|
||||
| Planck's constant | 6.626 x 10^-34
🗑
|
||||
| E = hv | E = hc/lambda
🗑
|
||||
| photoelectric effect | certain metals exhibit a photoelectric effect: they emit electrons when illuminated by light of certain wavelengths
🗑
|
||||
| dual nature | "wave" or "particle" characteristics.
both ideas are needed to fully explain light's behavior
🗑
|
||||
| diffraction | when waves of light pass thru such adjacent narrow slots, the waves are scattered so that the emerging light waves spread out
🗑
|
||||
| refraction | bending of light by a prism and the diffraction of light by a diffraction grating, a device w/ a series of parallel, closely spaced small slits.
🗑
|
||||
| quantize | To limit a variable or variables describing a physical system to discrete, distinct values.
(photons are the quanta of energy)
🗑
|
||||
| continuous spectrum | contains light of all wavelengths in the visible region
🗑
|
||||
| principle quantum number | each allowed orbit was assigned an interger, n
🗑
