Physics Laboratory Equipment (Applied Mech)

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 vertical plane and is rotatable about its axis. The

upper side of disc has a circular scale along its rim graduated 90º-0-90º- 0-90º × 1º and divides the disc in four equal quadrants with its center clearly marked. Shapes of various optical 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 reflective components – one each of plane glass mirror, polished semi-circular cylindrical mirror; and set of 6 refractive components, acrylic blocks (prisms) – one each of semi-circular, bi-convex, bi-concave, right angled prism, equilateral prism and trapezoidal prism. All optical elements provided with powerful magnets at their bottom for placing them securely on the disc in either of horizontal or vertical disc position. The bottoms of all refractive components are frosted to minimize internal reflections and revealing the path of light as it passes through.

The instrument has been designed to study concepts of motion on an inclined surface and its relationship to the friction. All metal construction provides sturdiness and durability to this apparatus. It comprises two metal boards, hinged at one end. One side of inclined board has a linear scale graduated at every 5cm to measure linear distance along its length and it can be inclined and fixed at any angle from 0-40º to the horizontal measured on the attached angle measurer. A vertical scale 0-25cm is also printed on the angular scale to measure the height of inclined surface at any point. The end of the inclined board features an adjustable pulley wheel from which masses, weight pan etc. can be suspended. A plastic trolley with hook and a pan with lightweight cord are also provided with the inclined plane. Size of inclined surface 80mm. Supplied without masses.
