Ad Astra Physics events

The latest report from students taking part in the Ad Astra Physics sessions is from Jonathan Sutton.

The picture on the Home page, shows a wave machine. A motor with a cam, oscillates a bar, which creates waves in the water bath. We tried various shaped barriers which directed the waves, it was really clever the way a curved one bounced all the waves in different directions! The picture here shows a spectrometer directed at a mercury lamp. All the different colours of ‘mercury’s’ light were split up, as it was a white light, most of the rainbow’s colours were there., however, when we tried a sodium lamp, the spectrometer mainly showed reds, oranges and yellows because the sodium light was an orange colour.
