## Quanta & Waves Resources

Resources: Notes and video (flash learning AH CfE Virtual Physics)

Read the notes, watch the video and answer the questions below, in a way that makes them form a good note about the subject.

1. What three pieces of key evidence didnâ€™t fit with classical physics?
2. In 1911 Rutherford put forward his model of the atom, a) State the important features of this model b) What provides the centripetal force for the electrons in this model?
4. State two changes with the black body radiation curve as temperature increases.
5. Describe the UV catastrophe.
6. Who helped solve the UV catastrophe and in what ways?
7. Which piece of the photoelectric effect experiment demonstrates that energy is not transferred as waves?
8. From the photoelectric effect state the link between the energy of the photon and a) the frequency of the radiation, b) the wavelength
9. What did Bohr postulate about angular momentum?
10. State the formula for angular momentum in Bohrâ€™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?
14. Explain the confusion caused when looking at the double slit experiment with single particles.
15. What happens when you observe an electron passing through the slit?
16. What two quantities cannot be measured together with much certainty and why?

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

Below are some cracking resources from Sally Weatherly, find her here!

Quantum Tunnelling – strange but true

Background

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.

# Focus

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 Iâ€™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. https://mrmackenzie.co.uk/advanced-higher/
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 donâ€™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.

## Project 2019+

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!

## Units, Prefixes, Scientific Notation and Uncertainties

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

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.

UPSN Uncerts These are the content statements covering this topic from the May 2016 Course Support Notes.

Uncertainties notes Mrs Physics’ AH Uncertainty Notes based on the pdf file by N Fancey and G Millar.

AH uncertainties experiments 2013  Experiment sheets produced by SSERC.

AH uncertainties tutorial 2013  Questions from Robert Gordon College.

AH uncertainties tutorial solutions 2013 The solutions from Robert Gordon College. Q1 updated. I’ll need to check through the rest.

Measurung gd practice

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.
