OBJECT

To verify Fresnel’s formula for the reflection of light by Spectrometer.

FEATURES

The complete Experimental Set-up consists of the followings :

Spectrometer standard : 6" dia circle reading 30 seconds. The objectives used in telescope and collimator are achromatic and provided with rack and pinion focussing arrangement. Telescope arm and prism table are provided with fine and coarse adjustment. The prism table is provided with three leveling screws and is engraved with concentric rings & lines. The scales and verniers are of stainless steel and are machine divided. Clamping devices are also provided to lock telescope and collimator after adjustment with prism clamping device and diffraction grating stand.
Sodium light source : Sodium light source complete with sodium lamp 35 watt with vaccum jacket, Transformer & Wooden Box having four holes with slide covers one each on every side at different heights.
A pair of Polaroids : Mounted on a graduated circular scale 360°, can be mounted on collimator and telescope by the help of three screws. Placed in velvet lined case.
Prism : Optically worked with two faces polished equilateral size 38mm x 38mm.
Reading lens : 40/50 mm diameter with handle.
Spirit level : 60/80 mm length
Weight : 14.2 Kg. (Approx.)
