Product Description
Leslie Cubes are metal cubes used in physics laboratories to demonstrate the principles of thermal radiation and emissivity. Each face of the cube has a different surface finish—such as polished, blackened, or white—which affects its heat radiation properties. When heated, Leslie Cubes allow students and researchers to observe how surface texture and color influence heat emission, making them essential for studies in thermodynamics and heat transfer.
