Harris Sound Wave Demonstration Set Age 5-6 heart (2-parts which are removable)Apparatus for investigating wave phenomena using sound. The efficient transducers may be driven by the output from a standard audio signal generator, and their sensitivity as receivers is such that they may be used directly on the 5mV input of an oscilloscope. Detailed equipment notes are provided covering investigations into: reflection and refraction; interference patterns in air; detection and measurement of phase differences in a signal received
