• Light interacts with different mediums by transmission including refraction , absorption or scattering. It depends on the medium. While doing so light follows a set of laws i.e. for reflection , refraction etc. Aim of this experiment is to show the peculiarities of light when passing through different shapes of glass.

• Item Code: PH-1018-C

A Optical Bench of plated brass rods mounted parallel in a pair of sturdy, metal legs, engraved scale, 0-100cm, on one rod, graduated in mm. Legs have leveling screws. Five heavy, brass riders included with index mark on one side, and a knob at the bottom to loosen / tighten their grip on the rods for adjusting their positions. Two riders have slow motion screws, providing sideways movement for axial adjustment of accessories. Accessories can also be adjusted for height. All accessories described in optical bench accessories are supplied with the bench.

Oxidized eureka wire wound on a porcelain tube is supported at both ends by durable, cast-aluminum, enamel painted end supports. A plastic sliding contact with laminated phosphor bronze strips is attached to the metallic bar, which in turn is mounted parallel to the tube. Three 4mm socket terminals with captive heads for electrical connection. Designed for Continuos use without overheating. Tolerance in nominal for marked value of resistance is ±5%. Resistance and current rating marked.
