See Enlarge Click to Enlarge Kundt?s Tube For the measurement of sound wavelength. Comprises of a glass tube 100cm length and 35mm diameter mounted on wooden bases. A rod and a piston moves inside the tube to vary the resonant length. See Enlarge Click to Enlarge Sonometer, 3-Wire Type A hollow wooden resonance box, with 100cm scale graduated in mm and fitted with three wires and keys. A pulley is attached to one end of the box. Complete with sliding adjustable. See Enlarge Click to Enlarge Sonometer, Spring Type A wooden baseboard 70x9cm mounted on four feet. At one end of the base are two 50N spring balances with hooks, and at the other end are two corresponding wrest-pins. Three bridges, one large and two small are provided. With two steel wires 0.3mm diameter x 1m. See Enlarge Click to Enlarge Resonance Tube Comprising two aluminium tubes telescoping into each other so that the column of air within the tube may be altered from 30cm to 53cm. Outer tube fits on a wooden base. See Enlarge Click to Enlarge Organ Pipe This wooden organ pipe is used to study relationship between the frequency of the sound produced with the length of the air column. Consists of a sliding rod with chromatic scale. When fully extended the organ pipe is 70cm long. See Enlarge Click to Enlarge Resonance Apparatus For easy measurement of velocity sound waves produced by tuning forks. Comprises of a glass tube 100cm long mounted on a stand which is fitted with levelling screws. The lower end of the tube is connected to a water reservoir by rubber tubing. The reservoir slides on a metal rod and can be lowered or raised for adjusting the length of air column. See Enlarge Click to Enlarge Whirling Table For use in both vertical or horizontal position, fitted with hand wheel and belt driven pulley, with adapter for clamping accessories. Over all height 43cm. See Enlarge Click to Enlarge Savart?s Toothed Wheels Set of four wheels of 75mm diameter, mounted on a spindle. Ratio of teeth being 4:5:6:8. For use with Whirling Table See Enlarge Click to Enlarge Ray Box and Optical Set A set of optical accessories for performing various experiments in reflection, refraction and colour. The key element is a ray box which has a metal lamp housing 155x70x55mm having an open front with finned sides to dissipate heat. It has four apertures one to accommodate the slit plate and another three for mounting colour filters. The two side apertures are fitted with hinged plane mirrors. With metal plate having single and triple slits and whitened on one side for use as returned image screen, 12V lamp and a lamp holder. Optical Accessories » 5 Prisms(Rectangular, semi-circular, triangular 60°x60°x60°, triangular 90°x60°x30°, triangular 90°x45°x45°) » 3 Cylindrical lenses (one double concave, one double convex, one thick double convex) » 3 Mirrors (curved parabolic, curved semicircular, mirror on stand) » 2 Slit plates » 8 Colour filters » 6 Colour cards Set comes complete with a replacement bulb but without power supply. -01 Complete Set -02 Raybox only -03 Power Supply -04 Replacement Lamp See Enlarge Click to Enlarge Direct Vision Spectroscope Useful for classroom demonstration and laboratory observations. Instrument provides a wide spectrum of any visible light source. Both emission and absorption spectra can be viewed. Features a 10x10mm Amici type 3-element prism train, telescopic focusing housed in brass body and variable optical slit adjustable by knurled head rotating ring. Wooden storage case included. See Enlarge Click to Enlarge D. V. Spectroscope With Wavelength Scale Portable and precise, the instrument provides direct wavelength readings of visible spectrum from 400nm to 750nm with each scale division representing 5nm. The spectrum is viewed in the plane of scale and for error free readings, D-line on scale can be adjusted. Incorporates a 10x10mm Amici type 3-element prism train, telescopic focusing housed in brass body and variable optical slit adjustable by knurled head rotating ring. Wooden storage case included. See Enlarge Click to Enlarge Junior Spectrometer Heavy cast aluminium alloy base integral with collimator tube support. Both the collimator and telescope have 175mm focal length and 25mm aperture object glass at their one ends. The collimator has precision slit and telescope an 8X Ramsden?s eye-piece at their other ends. Focusing is done by helical action device. The scale 175mm diameter is divided in degrees and is read to 0.1 degree (6 minutes of arc) with the help of the vernier fixed to the telescope arm. The scale can be rotated through 180? and locked in any desired position. The telescope has both the coarse and fine adjustment for exact readings. The prism table, 75mm diameter, has screwed holes for fixing prism and grating holders. It has lines marked to assist placing of prism with respect of table levelling screws. Prism holder can accommodate prisms up to 38mm high. Supplied with prism holder, grating holder and tommy bar for adjustment of optical axis. See Enlarge Click to Enlarge Intermediate Spectrometer This instrument is designed for high performance student use. It has cast aluminium alloy main structure. The collimator tube is mounted on the fixed pillar and telescope tube on the movable. Both the collimator and the telescope have 175mm focal length, 32mm clear aperture object glass at their one ends. The collimator has a precision slit 6mm high and telescope has Ramsden?s eye-piece 15X at their other ends. Both collimator and telescope have rack and pinion focusing and means for levelling their axes and squaring them to the axis of rotation. The scale 127mm diameter with protective shield is fixed to the telescope movement and the prism table is attached to the double ended vernier which reads to 1 minute arc. Both telescope and table can be rotated independently by hand about the same vertical axis. These can be clamped at the desired positions and adjusted precisely with the help of fine adjustment screws. Prism table is marked with lines to assist placing the prism with respect to the table levelling screws and has screwed holes for fixing prism and grating holders. Prism holder can accommodate prisms up to 38mm high. Supplied with prism holder, grating holder, magnifier glass, tommy bar for adjustment of optical axis and dense flint glass prism, equilateral 32x32mm. In plywood case.
