Reflection, Refraction, Diffraction

Educational Diffraction Gratings

Three diffraction gratings mounted on the same slide 100, 300, and 600 lines per mm. Individual gratings measure 1/2" x 3/8". Slide measures 3" x 1-1/4". More.

Newton’s Ring Apparatus

Display the interference pattern caused by the reflection of light between two surfaces. A convex lens mounted on top of a flat lens in a metallic frame with three terminals. When viewed with monochromatic light, it appears as a series of dark and light... More.

Replica Diffraction Grating Slides

Excellent for demonstrating the spectrum from various light sources. Gratings are mounted in a 2" x 2" slide frame for easy handling during classroom experiments. 13,500 lines per inch. Package of 25 slides. More.

Refraction Block

Acrylic refraction block. Measures 115 mm x 65 mm x 20 mm. All sides polished. More.

Reflection, Refraction, Diffraction Kit

These hands-on experiments explore the basic facts about how light travels. Covers reflection of light, light and color, refraction of light, theories of light, translucent and opaque objects, and much more. This kit is complete and ready for studen... More.

Refraction Tank with Laser

A self contained unit to measure and study refraction of light. Incident and refractive rays are easily seen and measured. Light rays air into water, water to air, and water in water can be studied easily with the help of built-in laser, as a light ... More.

Acrylic Refraction Cube

Perfect for index of refraction and total internal reflection experiments. Refraction causes the familiar mirage as we appear to see a nonexistent pool of water on a distant road on a very hot day. The ratio of the speed of light in a vacuum to the spee... More.

Plane Mirror Angle of Incidence and Reflection

No more use of prickly pins to demonstrate this important principle. This is a self contained unit with a light source to demonstrate that in plane mirror reflection, the angle of incidence is equal to the angle of reflection. It consists of a graduated... More.

Diffraction Materials Card

Is it a wave or a particle? Use this handy card containing five different materials to investigate the effects of diffraction, and explore the fundamental questions of quantum mechanics! This card can be used as a demonstration aid to discuss the qualit... More.
