Ray Box
To provide a simple means of producing single or multiple rays of light for use in elementary optics. Made of die-cast alloy, the ray box has an open front and vertical internal grooves to accommodate a slit plate and a cylindrical lens. Supplied complete with a plastic plate having single and triple slits, a 12 V 24 W SBC line filament lamp and a lamp holder.
Newton’s Color Disc
To demonstrate the discovery made by Newton that white light is composed of seven colors. Consisting of a pulley mounted on a metal stand, the seven colored disc is driven by gears connected to a hand driven wheel. When the colored disc rotates, the eye can’t distinguish between individual colors and perceive it as white color.
Spectrometer, Standard
Reads to 6 minutes of arc (0.1°) 170 mm diameter metal scale graduated 360° x 1°, independently rotatable, with locking screw, vernier attached to the telescope reads to 0.1° (6 minutes of arc). Collimator is mounted on a fixed pillar, with an achromatic objective of 150 mm focal length and 21 mm aperture, and has an adjustable slit 6 mm long. The telescope is on a movable pillar, with a fine adjustment screw, an achromatic objective of 170 mm focal length, 21 mm aperture, Ramsden eye-piece and glass crosswire graticule. Both collimator and telescope have spiral focusing system and have axis adjusting arrangement. The table has 3 leveling screws, with lines marked to assist prism placement. With prism and grating holders, one small screw driver and one Tommy bar for axis adjustment. Without prism.

Color Mixing Apparatus
The color mixing apparatus consists of three super bright LED’s RED, GREEN and BLUE to demonstrate the creation of secondary color with a combination of three primary colors. Intensity of these three LED’s are controlled with a microcontroller based controller. Intensity can be varied from 0-100 %.LED’s data can be stored to memory and later restored. The kit consists of two screens (one white Perspex screen and a black aperture screen) and a power supply.
Velocity Of Sound Apparatus
This dual purpose apparatus provides a compact facility for the measurement of the velocity of sound in air and also for the analysis of standing waves. It requires an audio signal generator and a dual beam oscilloscope (not included). A phase measurement between the speaker and microphone signals is made on an oscilloscope. The distance required to traverse through a 360° phase shift is noted. Knowing the frequency and distance, the speed of sound is computed. With the reflector in place a standing wave can be generated. Nodes and antinodes can easily be seen from the amplitude variations on the CRO.
Kinetic Theory Model
The Kinetic Theory Model apparatus is used along with the vibration generator to demonstrate the movement of molecules in a gas. An approximate relationship between the floating height, i.e., volume of the gas and weight of the disc, i.e., pressure of the gas can be observed. The platform has a rubber surface and small stainless steel balls are loaded into the tube. With the change in the speed of vibration generator, the heating of the gas stimulates resulting change in the agitation of the balls inside the tube. It comprises theory of piston, steel balls and a base or placing on an overhead projector.
