Product overview This instrument uses a projector to demonstrate wave interference, diffraction, and related wave phenomena. It is designed for straightforward classroom and laboratory use, giving clear visual results with simple operation. Key benefits Clear visualization: Projectorbased display makes interference and diffraction patterns easy to observe and explain. Easy to use: Simple structure and straightforward controls reduce setup time and make demonstrations accessible to students and instructors. Reliable vibration source: A DC motor with a flexible shaft drives the vibration source. This unique design improves conversion rates and provides stable, repeatable motion for consistent results. Low maintenance: Routine care and simple lubrication keep the instrument operating smoothly over time. Features and important attributes Function: Demonstrates wave interference, diffraction, and other wave phenomena with a projectorbased setup. Performance: Produces clear patterns that support teaching and experimental observation; vibration source driven by a DC motor with flexible shaft for stable performance. Compatibility: Suitable for classroom demonstrations, teaching labs, and basic experimental setups. Refer to the product specifications for exact compatibility with specific accessories or equipment. Size and material: See the included product specifications for precise dimensions and material details. Design: Simple mechanical layout for ease of use, with components arranged for straightforward assembly and maintenance. Care and storage recommendations Protect the instrument from dust and scratches during use and storage. For long periods of nonuse, remove the battery, dry the water tank thoroughly, place the vibration source and accessories in the component tank, and store the complete set in the original box. After extended use, add a small amount of instrument oil to each shaft to reduce friction and maintain smooth operation. Typical applications Classroom demonstrations: Show interference fringes and diffraction patterns during physics lessons to help students visualize wave behavior. Teaching laboratory experiments: Provide a reproducible, projectorbased visualization tool for lab exercises on wave optics and wave mechanics. Outreach and demonstrations: Use in workshops and public demonstrations to illustrate core wave phenomena in a clear and accessible way.
