This comprehensive kit with light/ray box and 29 optical components is ideal for performing a large variety of reflection refraction and color mixing experiments. The light/ray box consists of a 12V 24A halogen lamp producing convergent divergent or parallel beams. One end contains an adjustable cylindrical convex lens (for parallel beam) and on the other end a triple aperture system for color mixing experiments (lateral aperture is provided with adjustable hinged mirror). All apertures in the box are provided with vertical channels to hold slit plates and color filters. Kit comes with a comprehensive instruction guide with 18 activities Included in Kit: (1) Light/Ray box with hinged mirrors (1) Lamp holder (2) 12V (20W) bulbs (2) 4mm banana plug leads (2) Slit plates (8) Mounted color filters (8) Color cards (1) Rectangular prism (1) 45/45/90 prism (1) Equilateral prism (1) 30/60/90 triangular prism (1) Semicircular prim (1) Bi-concave lens (2) Bi-Convex lens (1) Plane mirror on stand (1) Parabolic mirror (1) Semi-circular mirror (1) Semi-circular Dish (1) Manual Required but not supplied: 12V DC power supply for ray box; ruler protractor and paper for activities Activities included in manual: 1) Diffraction 2) Angle of Reflection Using a Plane Mirror 3) Refraction of Different Shaped Prisms 4) Refraction (Snell s Law) 5) Index of Refraction 6) Dispersion of Light (Rainbows) 7) Dispersion of Infrared Light 8) Mixing Colors 9) Blocking Colors in a Prism Using Filters 10) Detecting Colors in Monochromatic Light 11) Study of Concave Mirrors 12) Study of Convex Mirrors 13) Spherical Aberration 14) Study of Convex Lenses (Ray Diagrams) 15) Study of Concave Lenses (Ray Diagrams) 16) How the Eye Works 17) How Glasses Work in Farsighted Vision 18) How Glasses Work in Nearsighted Vision
