The Physical World: Track 14

Video

This series of tracks introduces the basics of helicopter flight, quantum theory, special relativity, wave mechanics and particle physics, providing practical applications of physics and historical footage of Albert Einstein and Niels Bohr. Material is taken from The Open University course S207 The physical world.

Track 14: Waves: Sound waves

A look at sound waves, how they can be focussed and traditional methods of transferring sound at sea.
