About This Product
A stationary wave forms when two waves of the same frequency and amplitude travel in opposite directions along the string and interfere. Students use the apparatus to relate wave speed, frequency and wavelength and to see how tension and resonance shape the pattern. Educational Instrument can dispatch the Stationary wave apparatus to laboratories in Turkey, Italy, Libya, Oman, Burundi and Cameroon.
Frequently Asked Questions
How is a stationary wave formed on the string?
Two waves of the same frequency and amplitude travel in opposite directions and interfere, producing fixed nodes and antinodes along the string.
