Calculate the Doppler width of a spectrum line from a neon discharge tube operating at a temperature of 100°C. The value of the Boltzmann constant k is 1.38 x 10-23 joules per degree Kelvin (J/°K) and the mass of the neon atom is 3.34 x 10-26 kg. Take A = 600 nm and find the line width in both frequency and wavelength.
