  10. State the formula for angular momentum in Bohr’s model of the atom, (define each term)
  11. State the limits for the Bohr model of the atom
  12. Explain the observation made by GP Thomson in 1920 which led to further debate on the issue.
  13. What did de Broglie imply was the link between electrons as waves and particles?

Here is a nice little video on Standing Waves. Standing waves are formed when a wave interferes with its reflection to produce nodes and antinodes.

…..and here is the explanation for the standing wave video

Quantum Tunnelling – strange but true


What is the Uncertainty Principle? Minute Physics

Quantum Tunnelling is the process by which a particle gets across a barrier that it cannot classically pass.

It is related to wave-particle duality in that it is a result of the wave nature of a particle.

The probability of the particles getting through the barrier drops exponentially with the thickness of the barrier.

December 2020

Week 1: Get to know the Course


  1. Get to know the course, content and expectations
  2. Begin to understand Uncertainties, and how to quantify them
  3. Revise Higher work
  4. Get into a routine of expectations, good work routine, how to self study, how to seek help
  5. Review calculus and its role in AH physics.
  6. Begin to get to grips with section 1 in the compendium.
  7. Begin to investigate a possible project idea.

Success Criteria

  1. Score 90% in the quick quiz (If I can find out how to make them up!)
  2. Have a good understanding of your part in obtaining the best grade you can
  3. Start to make notes on compendium section 1.
  4. Have set up a learning routine for Project, Learning, Notes etc.


NB You do not have to do these in any particular order, although it would be easier to do some before the others!

  1. If possible download and print off the AH Compendium, relationships sheet and data sheet. If not can you download it in an editable form online
  2. Log into Scholar and check it out. I hope to be using it this year, so I’ll need a refresher too. The notes and questions can be a little awkward but it is a good background. Note there is a SCHOLAR introduction session on 6th May that I recommend you signing up for. Log in through your GLOW LAUNCHPAD
  3. Check out Mrsphysics AH section and familiarise yourself as to where to find things.
  4. Check other websites in the list that I am trying to make up on RESOURCES. I am trying to match this to the compendium but the IoP have been working on this for you too.
  5. Watch the video on Mr Mitchell’s introduction to AH Physics
  6. Watch the video on Mr Mitchell’s Units, Prefixes and Scientific Notation
  7. Watch the video on Mr Mitchell’s Significant Figures
  8. Watch the video on Mr Mitchell’s Greek Letters
  9. and one more watch the video on Mr Mitchell’s Use of Calculators
  10. Read the course content (course support notes)and the project and see if any of the potential projects takes your fancy.
  11. Get something to make notes in or on, if you don’t have access to a source of paper let me know by GLOW email. You need a jotter for notes, something for tutorials and a daybook for your project.
  12. Complete the Higher questions and see how many you can do without using your book.
  13. Read the document on Calculus (pdf) / Calculus (word) and work through that. There are homework questions for you to tackle in there. You will be marking these next week.

An adaptation of Tom Balanowski’s notes by Mr Bailey. This is a useful guide to teachers preparing students for their AH Physics Project. PLANNING is the KEY.

If you are not familiar with Excel can I recommend you spending a bit of time looking over the post in the BGE section (link below). I’ll add a further advanced part for you below.

Other packages are available and some are more robust such as R but I am not sure whether I will introduce that to you now.

Plotting graphs in Excel is coming this way soon!


Here is a little document to start you on some revision. The answers are given at the end, but don’t cheat.

Thanks to H Stark for her 10 week Revision Plan, you’ve just enough time if you start NOW!

Quantum Mechanics

  • I think I can safely say that nobody understands quantum mechanics.

But here is a great video to help you understand what is happening

Quantum Theory Full Documentary

The link below is to the brilliant video with Brian Greene- this should get you thinking. 

this link is set up so you miss the blurb at the beginning.

Or closer to home check out this video

Here is a link to brief notes on the important discoveries leading to the Quantum Mechanics ideas we know today.

The Sectrets of Quantum Physics

  • We have always had a great deal of difficulty understanding the world view that quantum mechanics represents. At least I do, because I’m an old enough man that I haven’t got to the point that this stuff is obvious to me. Okay, I still get nervous with it…. You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there’s no real problem. I cannot define the real problem, therefore I suspect there’s no real problem, but I’m not sure there’s no real problem.
    • Richard Feynman, in Simulating Physics with Computers appearing in International Journal of Theoretical Physics (1982) p. 471.
  • We choose to examine a phenomenon [Double-slit experiment] which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery. We cannot make the mystery go away by “explaining” how it works. We will just tell you how it works. In telling you how it works we will have told you about the basic peculiarities of all quantum mechanics.
    • Richard Feynman, The Feynman Lectures on Physics: Commemorative Issue, Vol. 3 Quantum Mechanics (1989) 1-1, “Quantum Behavior.”

Units, Prefixes, Scientific Notation and Uncertainties

Here is a link to a presentation that I gave for the IoP on AH Uncertainties.

The slides are 1GB, so you might want to ask me to share those some other way. Here is a pdf of the slides, including example SQA Uncertainty questions

Below is attached various useful documents to assist you in this vital part of the course. It is when you begin to use this material when going through your own experiments that it will become clear. Take time to read and understand it.

AH uncertainties summary notes 2013 These are a great set of notes produced by SSERC.

Here is a pdf of the talk I did for Physics teachers on Uncertainties in AH Physics. If you want the powerpoint you’ll need to get in touch as it is 1GB!

Below is the presentation. It was made for teachers, but there are quite a few bits suitable for students. Maybe I should edit it for students. Let me know..

Use this document very sparingly, it is not compatible with some of the AH mark scheme, especially in that it recommends you always round UP in an uncertainty. This is NOT what you should do at AH.- You’ve been warned! Contact me if you have concerns.
