Take 2 foam cups, 2 polarising filters, 1 protractor and you can make an analyser that measures the angle.
Then just download a Lux Light Meter on your phone to demonstrate Mallus' Law!
Light: Quantum Model
Light: Quantum Model
What evidence supports the particle model of light and what are the implications of this evidence for the development of the quantum model of light?
3 The quantum model of light.pdf50 000 kV? Surely you mean 50 000 V.
Also, did you earth the electroscope. No? Ok.
The spark must have visible light (we can see it), UVA, UVB and UVC, since it also gives out X-rays. The torch didn't work, so the frequency of the light from the torch must be less than the threshold frequency for zinc. That's logical.
An open-source simulation of the photoelectric effect, written at Singapore by Fu-Kwun Hwang, Loo Kang WEE, Tze Kwang Leong, can be found by clicking here.
This is a great explanation for you, especially if you are having difficulties with the Quantum Model of Light. Take notes while you watch this.
Light and special relativity
Light and special relativity
How does the behaviour of light affect concepts of time, space and matter?
See "Einstein Light" by UNSW explaining the "finer points of relativity in less time it takes than to eat a sandwich" (Scientific American, 2005).

This is a great explanation about the STAR Accelerator that we saw when we visited ANSTO this year!
