Exploring wave motion - for iPad/Mac/PC
by The Open University
What are waves and what happens to them when they pass through a gap? Do different sorts of waves behave in the same way? Dr Andrew Norton of The Open University uses a ripple tank to demonstrate some of the key features of wave motion, and show how waves spread out when they pass through an aperture. Using a laser and a diffraction grating, he shows that light waves spread out in the same way. The album draws on material originally created to support The Open University course Exploring Science.

Andrew Norton demonstrates the effects of changing the driving frequency of the oscillator that's creating the wave.
-
Apertures and diffraction
Andrew Norton shows what happens when waves pass through apertures of different sizes.
-
Diffraction of light
Andrew Norton uses lasers to show what happens when light passes through a small aperture.
-
Passing light through multiple apertures
Andrew Norton shows how diffraction gratings produce characteristic sets of light spots.
