Seeing with sound: sound lab tour

TLF ID L1302

Explore how sound travels as a wave. Examine diagrams and simulations to answer a series of questions about sound properties. For example, identify the effects of compression waves on the vibration speed of particles. Test the effects of changing wave properties: frequency, wavelength and amplitude. Transmit sounds in a range of mediums: air, water or steel. Examine definitions of wave properties and notice that sound travels faster in denser materials such as steel. This learning object is one in a series of five objects. The series is also packaged as a combined learning object.
