Concept Of Light Kit 

Kit is a collection of ray box, a set of a rectangular, a right-angled, equilateral, semi circular, two biconvex and a biconcave acrylic blocks, a plane mirror (75x100)mm, a concave mirror and a collimating lens with a singe/ triple slits useful for studying the fundamental concepts of optics using ray tracing technique. A Newton's colour disc for demonstrating that white light is a resultant of seven different colours comprising a multi coloured circular disc having sectors of various spectral colours. On rotating the disc at sufficient speed all the colours will be observed to disappear by merging into a single white colour and a die cast ray box have a 12V / 24W bulb provided with a two core lead terminating in a pair of 4mm plugs. Integral side rails are equipped with slots to accommodate the 45 mm wide collimating lens and double ended single / triple slit plates.
