The Doppler effect is one of the sources of the line broadening in atomic absorption
spectroscopy. Atoms moving toward the light source encounter higher-frequency radiation than atoms
moving away from the source. The difference in wavelength A experienced by an atom moving at
speed v (compared to one at rest) is A/ho=v/c, where c is the velocity of light. Estimate the line width
(in nanometers) of the lithium line at 670.776 (6707.76 Å) when the absorbing atoms are at a velocity
v is: (a) 2.47 x 10³ m/s (when T= 2000 K). (b) 3.08 x 10³ m/s (when T =3120 K).
