Ideal for teaching the principles of sound waves, this set enables clear demonstrations of wave phenomena in the classroom. Designed for secondary schools and colleges, it supports hands-on investigations into key physics concepts.

• Includes three transducers (usable as transmitters or receivers) and one control box.
• Transducers connect via 2m screened leads with 4mm plugs; control box has 1m screened input lead and two pairs of 4mm output sockets.
• Switch on control box allows phase reversal between outputs.
• Units housed in boxes measuring 100mm x 75mm x 40mm.
• Suitable for use with standard audio signal generators and oscilloscopes (5mV input).
• Comes with detailed equipment notes for a range of sound wave investigations.
