The first five energy levels of the hydrogen atom are at −13.6 eV, −3.4 eV, −1.51 eV, −0.85 eV, and −0.85 eV. The absorption spectrum of a hydrogen plasma is a continuous spectrum with dark lines corresponding to all the possible transitions between these five levels. Sketch the spectrum you would expect to see at wavelengths from 400 nm to 700 nm. You do not need to use colour in your sketch, but you should provide an x-axis with tickmarks and labels in nm, label the approximate red, green and blue regions, and label each dark line with its wavelength. Show your calculations of the wavelengths. (Hint: you should show three dark lines.)
