In this lecture we will discuss how the spectrographs work, derive the properties of diffraction grating, the resolution of the spectrograph and look at some example data. We will also discuss some instrumental effects and emphasize the difference between the spectrograph and filtergraph. • To take a look at a solar atlas, you can use this, fairly user-friendly website: http://bass2000.obspm.fr/solar_spect.php
