Get zinc and tick show photons.
Adjust light to UV and watch what happens. Explain why.
What happens at higher frequency light and why?
What happens if you apply a voltage across the plate and why?

The work function of a metal is 1.1 x 10 ^-19J. Calculate;

•a) threshold frequency

•b) maximum k.e. of emitted electrons when light of wavelength 520nm is shone on the metal.

Graph questions

What does this graph show?

Work out the gradient of your graph – what does it represent?

What is the x intercept?

How does the graph relate to the straight line graph equation y=mx+c?

What would the y intercept be?

Chance to spend two weeks at CERN this summer!

New summer camp for high-school students at CERN

S’Cool LAB Summer CAMP is an opportunity for 22 high-school students (aged 16-19) from all around the world to spend 2 weeks exploring the fascinating world of particle physics. The first S’Cool LAB Summer CAMP will take place from 23 July to 5 August 2017. 

If you  want to spend their summer at S’Cool LAB, CERN’s hands-on particle physics learning laboratory, for an epic programme of lectures and tutorials, team research projects and visits of CERN’s research installations, please visit the S’Cool LAB website to learn more about the camp, and how to apply.
