When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!
Electrons around atoms can absorb and emit photons of particular colours of light – see three different atomic models explain what's going on.
In the past, astronomers explored the universe with their eyes and optical telescopes, but what they could see was limited. Find out how radio telescopes have revolutionised the way astronomers 'see' the universe, allowing us to explore deeper into space than ever before.Watch this clip to learn about Australia's contribution ...
This six and a half minute video segment from Catalyst explains Earthshine as light from our own Earth reflected back from the Moon's dark side. A PhD student is studying it to learn about how light reflects from a planet that contains liquid water as well as land. Her work may one day lead to the discovery of other planets ...
This 12 minute video segment from Catalyst explains why photonics promises to remove bottlenecks and speed up the entire Internet by sending information with light rather than tardy little electrons. An excellent source of information on the current science for students of information systems.
View how scientists use underwater sound waves to measure ocean temperature changes in the Indian Ocean. The animations show how the technology called acoustic thermometry works. Australian scientists are working with a global network of 'listening posts' to monitor the long-term effects of climate change on ocean temperatures.
In this simulation students select to measure the voltage across one, two or three light bulbs in series to measure the voltage drop across one, two of three bulbs.
This 6 minute video segment from Catalyst is an excellent introduction to the science behind photovoltaics. A useful comparison of the efficiency of energy conversion. Discussion of other issues considered in producing devices to use renewable energy to make electricity.
This 10 minute video segment from Catalyst explains why the telescope is located where it is and relates it to the properties of light.
This 6 minute video segment from Catalyst explains how understanding the properties of sound and modelling has been successfully applied to create the ideal space for recitals.
