Student Ray Box Kit

The one-piece molded ray box contains a 7-lumen linear-filament light lamp (2.5V, 0.4A) that operates comfortably on two D-cell batteries, handily fitted into a compartment on the top of the unit. The kit includes interchangeable slits and a white plastic apron that clearly shows the path of the light rays. Lens models, a refraction tank, a mirror, and color filters allow your students to explore how light rays are affected by theses elements. Size: 7 x 7 x 6.5cm. Batteries not included.
