Featuring 16 vertical rods driven by eccentric discs and cams, it visually replicates sine wave patterns. A built-in rotational scale allows precise study of wave phase relationships, making it an essential hands-on tool for physics education and advanced wave mechanics demonstrations. ## Description Wave apparatus demonstration model shows the fundamentals of longitudinal and transverse wave motions. Made of high quality metal. Consists of a number of eccentric discs supporting a series of metal rods revolving on a handle.Handle is rotated to cause a series of cams to rotate which, in turn, cause a set of 16 vertical rods to rise and fall. Their motion follows that of a sine wave (vertical motion is caused by circular rotary motion). Transverse motion is visible by observing the tips of the rods (like a ripple in a water tank or a vibrating guitar string). A scale placed behind the handle divides the rotary motion into degrees of rotational angle so that the relationship or 'phase' between the rotary and the vertical motions may also be studied.A great way to demonstrate and explain various physics principles.Eisco Labs proudly manufactures its own products using state-of-the-art equipment, and following the highest standards of quality control. Each product is carefully designed by a team of laboratory professionals and experienced engineers with quality and durability in mind. They are manufactured with only the highest grade, raw materials and according to international quality standards to ensure that they can withstand use in even the toughest laboratory environments. Review: Highly recommend. - Bought this for an 8th grade science class. It was a hit!! Review: Mostly Good - Generally pleased. The baseplate arrived slightly warped, and the metal in one of the two screw holes that hold the sidebar on wasn't fully drilled out, but otherwise it has been successful in demonstrating transverse and longitudinal waves to my students. ## Features - ADVANCED MODEL || Wave apparatus demonstration model shows the fundamentals of longitudinal and transverse wave motions - HIGH QUALITY INSTRUMENT || Made of high quality metal - Consists of a number of eccentric discs supporting a series of metal rods revolving on a handle - SHOWS MULTIPLE WAVE MOTIONS || Handle is rotated to cause a series of cams to rotate which, in turn, cause a set of 16 vertical rods to rise and fall.

It was a hit!! ### ⭐⭐⭐⭐ Mostly Good *by J***. on February 13, 2025* Generally pleased. The baseplate arrived slightly warped, and the metal in one of the two screw holes that hold the sidebar on wasn't fully drilled out, but otherwise it has been successful in demonstrating transverse and longitudinal waves to my students. ### ⭐ Neat idea, but poor quality control. *by R***. on November 28, 2019* Great concept, but arrived with a bent rod that detracts from the compression wave. Disappointing quality control on what could have been a wonderful machine and purchase. ## Frequently Bought Together - EISCO Wave Apparatus Demo, Metal - Longitudinal and Transverse Motion - Advanced - BNTECHGO 24 AWG Magnet Wire - Enameled Copper Wire - Enameled Magnet Winding Wire - 4 oz - 0.0197" Diameter 1 Spool Coil Red Temperature Rating 155℃ Widely Used for Transformers Inductors - EUDAX School Physics Labs Basic Electricity Discovery Circuit and Magnetism Experiment kits for High School Students Electromagnetism Elementary Electronics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/25221121-wave-apparatus-demo-metal-longitudinal-and-transverse-motion-advanced](https://www.desertcart.vu/products/25221121-wave-apparatus-demo-metal-longitudinal-and-transverse-motion-advanced) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
