Sound waves measure ocean temperatures

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.

Breaking glass with sound

Sound energy travels in waves and is produced when an object vibrates and causes air particles to move and collide. The frequency of a sound wave depends on the speed of the vibrations, which we hear as higher or lower sounds. Watch this clip to investigate how string instruments can shatter glass through the power of their ...
