total internal reflection

By coincidence (pardon the pun!), both Int2 and S3 have reached the stage of investigating total internal reflection at the same time.  Here is a photo showing total internal reflection of a laser beam in a tank of water.

I’ve put together a short video showing total internal reflection in a semicircular block and a perspex model of an optical fibre.
