Homework 8. Spectral Lines
Use the diffraction grating handed out in class (10/13) to look at
spectra of several different light sources, including an ordinary
light bulb, a neon sign, a streetlight, and two more of your own
chosing. Which of these sources produce a continuous spectrum, which
produce bright spectral lines, and which produce both? Give your
answers below, and sketch the spectrum for each.
