NYSF 2017 physics interest group, Wu was treated to a visit to the Physics Education Centre at the Australian National University. The visit was well received by all the students as they performed experiments about the physics of light and asked thoughtful questions of the physicists.
Led by Mr Andrew Papworth (a long-term and committed NYSF supporter) with a team of postgraduate students, the participants were guided through first and second year university experiments. The participants used a spectrophotometer to investigate the wavelength of light emitted by different elements, using several known sources to find the composition of an unknown lamp. Next was a series of experiments with lasers to learn about the Michelson interferometer and then one to learn about the detection and absorption of gamma rays.
Next was a series of ‘magic tricks’ were the students learnt about resonance tubes, magnetic breaking and the polarisation of light. A visit to the ANU gravitational wave lab gave the students an inside view of the discovery of gravitational waves, how gravity has been calculated to 19 decimal places and the implications of this research in the real world, in particular in regards to gravity mapping. The participants also asked some meaningful questions about general and special relativity which they found particularly fascinating.
we were shown a variety of actual things which could be implemented into the world
The group left the visit inspired with one participant, Wade Clark, saying that he “really enjoyed that we were shown a variety of actual things which could be implemented into the world rather than just theoretical physics which we find at school. Things that actually will create a difference in the world rather than just sit on a shelf somewhere.”
