The Standard
Assignments
Photoelectric Effect (ESA p183 - 191)
Below are three video lessons covering everything you need to know about the photoelectric effect, and here is a link to an excellent article providing thorough notes https://www.khanacademy.org/science/physics/quantum-physics/photons/a/photoelectric-effect.

An excellent simulation to help you visualise the photoelectric effect. You will need javascript enable to run this.
A great video explaining the photoelectric effect, including what science expected to happen (wave model of light) and what really happened due to the particle model of light... oh and the music is good too

Atomic Spectra (Esa p191 - 201)
The following link provides excellent notes on atomic spectra. Very thorough and clearly explained https://www.chemguide.co.uk/atoms/properties/hspectrum.html
The two videos below cover energy levels and atomic spectra in detail. You will need to supplement these videos by reading the notes on the relevant pages of your ESA study guide.
Have a play with the applet below to test the concepts of emission spectra.
Here is another simulator to show how electrons behave when interacting with photons. If you increase the energy of the incoming photons high enough the atom will be ionised.

The following videos are at a higher level than is required for this standard. They are very good to help your understanding of atoms and how they really work compared to the lies we have been telling you...

Nuclear Reactions (ESA p203 - 214)
In the video below, Doc Physics takes us through mass/energy equivalence and the binding energy of nuclei.
Experiment with the interactive simulation below covering nuclear reactions.
A good video explaining binding energy per nucleon graphs
|
An interesting 1952 cold war propaganda film about nuclear physics. It has a good explanation of binding energy
