Ps2 The Doppler effect is one of the sources of the line broadening in atomic absorption spectroscopy. Atoms moving toward the light source encounter higher ā frequency radiation than atoms moving away from the source. The difference in wavelength Dl experienced by an atom moving at speed v (compared to one at rest) is Ī» Ī» Ī = v c , where c is the velocity of light. Estimate the line width (in nanometers) of the strontium line at 460.733 nm when the absorbing atoms are at a temperature of (a) 1975 K and (b) 3150K. The average speed of an atom is given by Ļ = 8 kT v m , where k is Boltzmannās constant, T is the absolute temperature, and m is the mass
