Question

2. This question relates to the Doppler broadening of spectral lines — you may want to read the very last part of Chapter 5 before attempting this question. The so-called Sodium D lines (rest-frame wavelength ? = 5900Å) are observed in the atmospheres of many stars, including our sun. The surface temperature of the sun is ~6000K; estimate the Doppler broadening (FWHM in angstroms) of the Sodium D lines in the sun.

Step 1

Step 1: Calculate the value of \( W_0 \) using the formula \( W_0 = \frac{2 \cdot 22 \cdot 3 \cdot 10^8}{7 \cdot 5900 \cdot 10^{-10}} \). Show more…
