PAIR OF NARROW PRISMS
Designed to provide a progression of ideas from the principles of refraction in prisms to the properties of lenses. Each Perspex prism is in the form of a narrow isoceles triangle 15 x 60 x 20 mm (base x height x thickness). When placed base to base a convex lens may be simulated, and a concave lens when vertex to vertex. |
