The attached file is a summary of the entire AH course from the kind people at Hermitage Academy. Have a read through it and try some of the problems before you sit the prelim on Monday.

AH – doppler effect
Have a look at these problems on the Doppler effect.
AH – describing waves
These notes cover the learning outcomes specific to describing waves (not the whole of unit 3!!!)
AH – magnetic fields
These notes are designed to give you practice at solving problems involving the movement of charged particles in magnetic fields.
AH – electric fields
Here are some problems to get you a bit of practice with electric field questions ahead of the unit 2 nab next week.
Nuclear fission

We’ve discussed nuclear fission in class this week. This is the process where an unstable nucleus splits into 2 or more smaller nuclei. The new atoms produced are called daughter products of the fission process. The University of California has a good animation of the fission process with commentary. I have also included a link below to a nice animation from atomicarchive.com.
Rutherford’s scattering of alpha particles
In the last part of the Higher course, we looked at the structure of the atom. Rutherford scattering of alpha particles fired at a very thin sheet of gold foil provided the evidence to develop our understanding of the atom from a “plum pudding” model to a “nuclear” atom – where most of the matter and mass are concentrated in the centre, or nucleus, of the atom.
There is a really good youtube video about Rutherford & alpha particle scattering – watch the first 5 minutes only, it goes on to another topic after that. You can also follow the link below (the download link at end of post) to watch an animation of the alpha particle scattering experiment and follow how the results changed our view of the atom.
AH – unit 1 summary notes
These notes cover the whole of the first unit.
