IB Physics: Resolution

UtilisationsMaybe not a whole lessons worth but quite a difficult topic so worth spending some time on. A good introduction is to draw two fine dots on a paper and ask the class how many dots there are. This has limited success, if the dots are too small no one can see any dots bit if to big everyone sees two. You can come back to calculate the closest resolvable distance after you have done the Rayleigh criterion.
