Ultrasonic System

Ultrasonic Transmitter And Receiver Operating In 40 Khz Frequency Region Enclosed In Plastic Enclosures (142x80x43) Mm Approx. 2 Khz Modulating Frequency Is Transmitted By Ultrasonic Transmitter And Detected By Receiver, Which Amplifies The Sigl And Drives A Interl Loudspeaker. Output Sigl Can Also Be Visualized On A Cro For More Quantitative Measurements Through 4Mm Sockets Fitted On The Receiver. Transmitter Is Supplied With Two Ultrasonic Transducer, Both Can Be Switched On Simultaneously When Required To Produce Two Coherent Sources. Interference Pattern Can Be Dramatically Demonstrated And Simplifying The Youngs Slits Experiment By Using Waves Rather Than Light On Moving The Receiver Along A Line Parallel To The Sources. The System Uses The Sound Waves Above The Hearing Threshold And Demonstrating The Reflection Properties Linked With Sor Etc. (Ultrasonic System)
