We’ve been talking about colour tv in class and I found a few items you might want to look at. First of all, the website I used in class is available here and there is further information on combining colours here.

There is also a helpful animation of the shadow mask that stops the three electron beams from reaching the wrong phosphor dots.

We don’t need to cover chemotherapy as part of the Standard Grade Phyics course but I thought you might be interested in how it works, now that we have looked at the use of Radiotherapy.  The attached pdf file contains some notes on chemotherapy taken from the CancerHelp UK website.
