Some display problems
On two different browsers (IE 7 and Firefox 2.0.x) I cannot see the content of the pop-up balloons in the exercises. Only white boxes appear under the mouse (e.g. the exercise at the end of the "Interference and diffraction" section).
Also some characters display as small boxes (e.g. in the "Interference and diffraction" section in "d sin(theta)= n lambda", "n" displays as a box).
Otherwise a simple and clear short review of the topic.
