Having previously covered waves in general (https://physbang.com/2023/04/13/key-facts-waves/) it is now time to look at electromagnetic waves in particular as this is a topic in its own right. Electromagnetic waves are created by the movement of electrons in different situations. The electrons can be moving in an electric circuit, to produce or receive radio waves, or … Continue reading Key Facts: Electromagnetic Waves
BBC Bitesize – Paper 1 Revision
November's trial examination will include everything in Paper 1. This means everything that was due to be covered in Y10 - and that in turn means a fair amount of content that you had to study at home during the lockdown. Now you are about to be tested on what you know and it is … Continue reading BBC Bitesize – Paper 1 Revision
Home Study Projects
Constantly going over things that you have already learned can get a bit boring so if you want to extend your knowledge over the summer holiday then it's a good idea to do so using some fresh material. Finding suitable resources can be tricky so let me suggest some materials that are provided online at … Continue reading Home Study Projects
Surface Colour and Cooling
In the same way that surface colour affects the rate at which objects heat-up and the maximum temperature that they reach (as discussed here) so too will the surface colour affect the rate of cooling. As before, there is a standard experiment that you are expected to know and a typical set of curves that … Continue reading Surface Colour and Cooling
Surface Colour and Heating
Most people say you shouldn't go out on a summer's day wearing black because you will get too hot. It would be much better to wear white as this will keep you cooler. But is that actually true? We can test this idea using two boiling tubes that have been sprayed to have different surface … Continue reading Surface Colour and Heating
Six Impossible Things
Most of the physics you learn at school hasn't changed for hundreds of years. It is important stuff because we know that it works and it underpins a lot of the modern world. But that doesn't mean it is right. This is the point that is made in John Gribbin's new book, Six Impossible Things. … Continue reading Six Impossible Things
EMS Short Study Course
NASA has created an excellent self-contained short study course that covers the electromagnetic spectrum (EMS) from an astronomy perspective. This resource therefore has double value for GCSE Physics as it supports learning across the topics of both waves and space. The course comprises four introductory sections, eight units on parts of the electromagnetic spectrum and … Continue reading EMS Short Study Course
Try This At Home (IoP)
You could be studying physics every day but it would be better to have some down time! So here are some ideas for experiments that you can do at home when you are taking a break from your studies. These things aren't rocket science; they're about waves, forces and the shape of space (actually a … Continue reading Try This At Home (IoP)
