Comprising a hollow wooden box 1140x125x100mm with 2 meter rules divided in mm. Two wires of brass & steel attached to fixed bridge & tensioned by fine adjustment pegs. Two movable bridges, pulley & fixed screw to enable a third wire to fixed for tensioning by masses. Complete with two bridges.
A metal screen 75mm diameter, with an adjustable iris diaphragm mounted in the centre, giving a maximum aperture of 6mm. The disc is mounted on a 6mm brass rod & the optical centre height is 80mm approx.
A Ray box kit also known as a Light box kit is used to understand various optical properties .These optical properties are made practically visible and more erudite using a ray box/light box kit. A ray box/light box kit is a simple enclosed box (one side open) consisting of an incandescent bulb, various detachable slides, lenses, mirrors and color filters. These slides and lenses when used individually in a ray box/light box produce various optical properties which are determined by analyzing the distinct paths of light rays coming out of the ray box/light box.
Designed to operate on a 12V AC supply and uses the mains frequency as its timing standard. The unit is housed in a moulded case including mounting flanges. The top of the case carries a tape guide which incorporates a carbon paper disc support and an adjustable anvil for the striker point. This instrument is use for the measurement of velocity and acceleration, using timing marks made on a moving paper tape by a vibrating striker. All moving parts are fully enclosed and a pair of 4mm sockets is provided on the side of the case for connection of the electrical supply.
This set includes a friction block and a friction board, both made of wood. Students can vary the weight or area of contact to see their impact on the friction force. Comes with three 50gm weights and a 100gm spring balance.
Robust, standard pattern timer for general classroom use. It has a hand precision spring movement and large start and reset triggers for operation.
On clamp, light alloy, 50mm dia. held in metal bracket, with two clamping screws for bench and rod support respectively. Bracket may be clamped to a bench edge or similar 38mm thick support, screwed to flat surface, or held on 113mm dia. support rod.
IME type, Improved design, plated steel, with dual scale 0.15cm x 0.1mm and 6 x 1/128 inches, provided with thumb movement for easy motion of jaws, in plastic case.
Consists of a metal tank 150x90x100mm has five apertures on one side through which 100x3mm metal rods of copper, brass, aluminium, iron & glass pass. The outer end of each rod has a cavity. When the low melting point paraffin wax is placed in the cavity, the different metals melt the paraffin at different rates.
A casted brass gauge with wooden handle, sliding fit over ends of bar & with hole 12.5mm bore in both arms & a mild steel bar 110x12.5mm with wooden handle.
Variable Plate Condenser In box with two terminals in bakelite front panel which is directly calibrated range 25 p.f. to 500 p.f. or 50 p.f. to 1000 p.f.
Spade Terminal Adapter To convert ordinary screw terminals for use with 4mm plug connectors. This adapter consists of a standard type of spade terminal integral with an insulated 4mm socket connector. A transverse 4mm connection hole is also provided enabling two connections to be made to the adapter.
Variable upto 345 ohms at 1.2 A rating for use as a series resistor or a potentiometer. Enclosed type, in metal case with windings on porcelain former 350mm long x 56mm diameter; three 4mm socket terminals & four mounting lugs tapped.
Molecular Movement Tube Straight tube filled with glass beads and mercury under high vacuum. When heated on spirit lamp, the glass beads give exact replica of the Brownian movements, visible to naked eyes.
Comprises a container 90x90x150mm. Rim shaped to hold the zinc rod to accommodate the cathode, a porous pot containing a carbon rod with terminal with a mixture of powdered carbon & manganese dioxide depolarizer. Requires approx. 500ml ammonium chloride electrolyte with zinc rod & porous pot but without electrolyte. The cell produces an EMF of about 1.5 volts.
Made of brass, the design of the slots ensures that the masses may be easily removed and replaced but will not fall off accidentally. Having 1 hanger and 9 slotted masses in each set.
