Equilateral prisms clear with long sides for refractive index measurements, a trapezoidal prism with a frosted base to show ray paths inside the prism. 75 mm side, 9 mm thick
For exploring the various concepts of optics involving reflection and refraction using ray tracing technique. Comprises a sheet metal disc, about 30cm in diameter, painted white at the top with clamping assembly at its underside for mounting it on a vertical support rod in either of horizontal or veritcal plane and is rotatable about its axis. The upper side of disc has a circular scale along its rim graduated 90-0-900-90 and divides the disc in four equal quadrants with its center clearly marked. Shapes of various opcal elements also clearly marked on the disc to facilitate their placement while performing experiments. The clamp at the underside has metal bar projecting radially outside with adjustable lamp holder mounted at the other end with an adjustable collimating lens to get divergent, convergent or parallel beam as required. A rotatable disc attached in front of collimating lens provides option of single, double, triple or quadruple slits for range of experiments. Complete assembly mounted on stable cast metal heavy base. Supplied complete with reflecitve components one each of plane glass mirror, polished semi-circular cylindrical mirror; and set of 6 refracitve components, acrylic blocks (prisms) one each of semi-circular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism. All opitcal elements provided with powerful magnets at their boom for placing them securely on the disc in either of horizontal or vertical disc posiiton. The booms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through.
