Several absorption transitions between energy levels of Na are indicated in the figure
below. Some of these are allowed and some are not. Find the four allowed absorption
transitions and, by dragging and dropping a tick or a cross into the box next to the line
representing each transition, indicate them in the figure. You need to put either a tick or
a cross on all boxes.
