Q2Q Prac 1






You will be instructed on the use of a prism spectrometer, and how to determine the wavelength.



Quanta to Quark




In 1911 Rutherford Used a Radium Bromide alpha particle source (He++) and formed it into a beam. As most passed throught he foil with out deflection most of the atom was empty space (?) The one in 10,000 that deflected of a + charged nucleus.







The above are spectral lines of Hydrogen. Use E =hf to analyse the importance of this spectrum.

Research Bohrs Postulates.

About Me

My photo
I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
