Jon Chase meets a range of individuals using wave science to do things in the real world. Young opera singers attempt to match the fundamental frequency of a wine glass - and then destroy it with the power of their voices. Doctors use destructive waves to cure a painful medical condition by sending sound waves deep into the body. A team of young engineers harness the power of the sun to take their futuristic car across Australia. But as Jon discovers, we are solar-powered too. Prize-winning photographer Reece McCready has learned how to control light waves to create stunning images. Jon joins him in a portrait session to see how reflection and refraction are central to photography. In another studio, Jon joins singer Charlie-Anne Bradfield who is recording a new track. Jon makes his own microphone and loudspeaker to show how sound waves go from guitar to recording. On one of the best surf beaches in Britain, Jon joins international surfers to discover exactly what a wave is, why it is that the waves travel but the water does not, and how many kinds of wave there are. This programme is for KS3 and KS4 physics.
