The demostration meter is used to demostrate the working principle of AC and DC Ammeter, Voltmeter and Galvanometer with the help of interchangeable plastic Scales. Amagnetically damped spring controlled moving coil movement is housed in a plasic case with glass front and rear panel. A pair of 4 mm socket terminals is give on the right side to apply voltage and current. A special locking arrangement and a centrl / side zero adjustment control is given on the left side with the help of two knobs.
The interchageable scales are boldy marked on both sides enabling the class to view from the front and the demostrator from the rear. Each scale is fitted through a slot on the right side of the case and has a plug connector which also serves to locate and align the scale positively in position. Locking system is provided to lock the pointer to aovid damage is transist.

To demonstrate the phenomenon of interference of light using bi-prism and to understand the concept of interference, image formation width of fringes. It consists of 1 1/2 meter long stainless steel double rod optical bench with following accessories.Biprism holder having fine radial motion by screws. Adjustable slit with ground ss jaws Micrometer Eye Piece Ramsden’s 10x, carried on a slider which moves along a micrometer screw.Automatic lens holder with spring action for equal opening and closing of both ends
For demonstration of interference, diffraction and holography. Laser source and switch mode power supply are housed in a thick aluminium box with a hole through which laser beam comes out. The laser unit is mounted on a precision 1 meter double rod SS optical bench. Intensity of laser beam is 2mW and it is red in color. Input power is 220V AC. Minimum operating life is 15,000 hrs. and shelf life is 10 year. The unit is supplied with single slit and diffraction gratingAlthough this is a very safe equipment to handle still a few precautions will ensure proper safety and long life viz. Operate the laser at least once in a fortnight
