Description

This consists of a self-contained transmitter and receiver operating in the 40 kHz region. The transmitted wave is modulated at a user-controlled variable frequency of about 2kHz and this is detected by the receiver which amplifies the signal and drives a miniature integral loudspeaker. Both transmitter and receiver are contained in separate plastic enclosures 60 x 100 x 25mm which contain all electronics and 9V batteries. The receiver has front panel 4mm sockets so the output can be monitored on an oscilloscope for quantitative measurements. It is ideal for demonstrating sound waves above the hearing threshold and reflection properties associated with sonar etc. A special feature is the second transducer on the transmitter which can be switched in when required to produce two coherent sources. By moving the receiver along a line parallel to the 2 sources interference patterns can be dramatically demonstrated, simplifying Young's slits experiment or enabling it to be demonstrated using waves other than light. Complete with batteries, instructions and suggestions for use.
