? BEXCO Hollow Prism with Stopper - 2x2x2-Inch Equilateral for Physics Lab The BEXCO Hollow Prism is an essential piece of apparatus for teaching and demonstrating fundamental concepts of light and optics in physics classrooms and laboratories. Designed for experiments involving the refraction, reflection, and dispersion of light. ?? Key Features for Experiments * Hollow Design: Allows the prism to be filled with different liquids (like water or oil) to demonstrate how varying media change the angle of refraction. * Equilateral Shape: Features three equal sides (2x2x2-inch nominal size) which are polished for minimal light scattering and maximum clarity. * Stopper/Hanger Included: The attached stopper allows the prism to be sealed when filled with liquid, and can also be used for suspension during experiments. * High Clarity Material: Provides excellent light transmission for sharp, clear spectrum and refraction demonstrations. ?? Ideal for Demonstrating: * Refraction of light through different media. * Internal Reflection and Critical Angle. * Dispersion of white light into the color spectrum. ?? Technical Details * Instrument Type: Hollow Equilateral Prism with Stopper * Brand: BEXCO * Nominal Size: 2 x 2 x 2 Inches (Side Lengths) * Use: Physics Laboratory and Science Education Bring light experiments to life!
