Sound & vibration
Two mechanisms demonstrate the relationship between vibration direction and wave travel.
THE PRODUCT IN MOTION
Two mechanisms demonstrate the relationship between vibration direction and wave travel.
Video & text guideTHE ACTIVITY & MECHANISM
In a longitudinal wave, the medium oscillates parallel to the direction of propagation. In a transverse wave, it oscillates perpendicular to that direction. The moving rods model these two relationships, helping visitors distinguish local vibration from the travel of a wave pattern.
Turn the handwheel.
Observe the two moving mechanisms.
Compare motion along and across the direction of travel.
REFERENCE & PROJECT SCOPE
Use the reference dimensions and operating information to plan the exhibit. The agreed project drawings define the supplied configuration, installation interfaces and service access.
Length × width × height in mm, including the cabinet. Final project drawing governs.
BEFORE AN ENQUIRY
24 months of complimentary spare-parts support, remote technical guidance and long-term after-sales support. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
Explore the supportYes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.
How prototype testing & samples workDiscuss the appearance, interpretation, controls and installed configuration of Longitudinal & Transverse Waves for your audience and space.
The gallery labels photographs, video frames, renderings and the dimension drawing. Physical footage is identified separately.
