Ray Box and Optical Kit. This comprehensive kit is perfect for performing a variety of reflection, refraction, and color mixing experiments. Here are the key details:

1. Ray Box:

   • The ray box is equipped with a 12V, 24W halogen lamp that produces convergent, divergent, or parallel beams.
   • One end of the ray box features an adjustable cylindrical convex lens for creating parallel beams.
   • The other end has a triple aperture system for color mixing experiments, complete with an adjustable hinged mirror.
   • All apertures in the box come with vertical channels to hold slit plates and color filters.

2. Optical Components (Included):

   • Lenses: Four 50 mm diameter ground glass lenses with focal lengths of +100, +200, +250, and -150 mm.
   • Concave/Convex Mirror: A mounted 50 mm diameter concave mirror that focuses on the half-screen.
   • Adjustable Lens Holder: Easily mount circular lenses between 20 and 75 mm in diameter.
   • Ray Optics Kit: Explore ray optics with various accessories, including concave/convex lenses, mirrors, and an acrylic rhomboid prism for studying refraction.
   • Color Filters and Color Cards: Essential for investigating light and color properties.

3. Comprehensive Manual:

   • The kit includes a detailed instruction guide with 18 activities to help you understand and demonstrate geometrical optics concepts.

4. Requirements:

   • A 12V DC power supply is necessary for the ray box.
   • You’ll need a ruler, protractor, and paper for the activities.
