emission and absorption lines
gases
_____ under pressure produce a continuous spectrum
solids; liquids
______ and _______ heated at very high temperatures produce a continuous spectrum
white light
__________ is considered the continuous spectrum because it consists of all frequencies
absorption
__________ lines appear at the exact same frequencies as its emission lines
visible
range that the Balmer series exists in the spectrum
infrared
range that the Paschen series exists in the spectrum
emission spectrum
spectrum emitted by electrons returning to lower energy levels from higher energy levels; also called line spectrum
absorption spectrum
spectrum that appears to have dark lines against a continuous spectrum, which the dark lines are this spectrum; electrons of a cooled gas go from low to high energy
continuous spectrum
spectrum that consists of a continuum of frequencies of electromagnetic radiation
emission
the ________ spectrum appears as a series of bright individual emission lines when the light is viewed through a spectroscope
ultraviolet
the range that the Lyman series exists in the spectrum
continuous, emission, and absorption
three types of spectra that can be emitted by an element
Balmer series
transition of electrons from higher energy levels to n=2 generate spectral lines; first seen by Johann in 1885
Lyman series
when electrons in a hydrogen atom jump from higher energy levels to ground state (n=1); first seen by Theodore in 1906
Paschen series
when electrons move from higher energy levels to n=3; first seen by Friedrich in 1908
