Your assignment will be based on an optoelectronics topic. You will get some ideas for practical work by downloading this booklet. I have attached a copy of the Scholar notes for unit 3 of the CfE Higher course. You will find background physics with appropriate energy band explanations on pages 103-142. Don’t print this document, ... Read more
Thanks to Mr Ferguson for sharing his copy of the marking instructions for the 1996 Higher paper, it’s the only one I didn’t have! You’ll find a link to his answers on the Higher revision page.
The Q&W unit assessment is next week. Here are the Scholar notes to help with your revision.
Remember that your unit assessment for P&W will take place at the end of this week. The attached notes might be helpful during your revision.
An electric field can be used to accelerate charged particles. Conservation of energy tells us that work done by the electric field = change in the particle’s kinetic energy The speed of the particle can be determined if its charge and the accelerating voltage (potential difference) are known. The notes attached to the end of this post ... Read more
At the end of Our Dynamic Universe, we considered big things like stars, galaxies and the Universe itself. Now the Particles and Waves unit brings us to particles so small we need groups of them just to make a single atom. Is there a connection? Why do we study particles? from mr mackenzie on Vimeo. The Standard Model An elementary ... Read more
A set of summary notes for the 1st unit of Higher Physics is attached below. Don’t forget that BBC Bitesize and Scholar are also available for revision.
The Scholar tutorial is on Monday 14th November, starting at 6pm. You can join the room from 5.30pm using the link on this page.
Twinkle, twinkle little star, How I wonder what you are. Giant thermonuclear reaction; Held by gravitational attraction. Twinkle, twinkle little star, You look so small ’cause you’re so far. As you burn through constant fusion, Your twinkle’s just an optical illusion. That happens when your light gets near; distorted by our atmosphere. Twinkle, twinkle little ... Read more
Our Sun is a typical yellow star, so its emission would be represented by the middle star in this image. image courtesy of kstars, kde.org – colour is exaggerated The colour of a star also tells us something about the expected behaviour of a star, it’s lifetime, and destiny. This is achieved by plotting stars ... Read more
