EM flashcards
What 3 things differentiate EM waves?
frequency
wavelength
NRG
C=Av is an equation for?
Speed of wave. (c)
A= wAvelength
v= frequency
Define frequency
of waves per second
Continuous spectrum
continuous band of colors from red to violet produced when white light passes a prism.
Bright line spectra
when element is heated or gas is stimulated by cathode ray, the element produced the spectra. Ea. is unique.
Spectroscope
device that splits light into its component frequencies
Wavelength
distance between one wave and the next.
INVERSELY PROPORTIONAL between FREQUENCY
Quanta or Photon
fixed amount of nrg that can be gained or lost by an atom,
Depends on frequency of light
Ground state
when all electrons are in lowest possible NRG levels
Excited state
when e- are excited by RADIATION OR ELECTRICITY
What happens when e- returns to ground state?
releases photon light nrg
