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
