About This Product
The detailed equipment notes cover reflection and refraction, interference patterns in air, detection and measurement of phase differences in a signal received by two receivers, and measurement of wavelength using the phase difference between transmitter and receiver. Export supply of the Sound Wave Demonstration Set can be arranged to laboratories and schools in Fiji, Central African Republic, Iceland, São Tomé and Príncipe and Malaysia.
Frequently Asked Questions
Q1. Can the receivers connect straight to an oscilloscope? Yes. Their sensitivity as receivers allows them to be used directly on the 5 mV input of an oscilloscope.
