A Robust light box in matt black finish with a 12 V 24 W axial filament lamp with flexible leads. One end of the box takes a cylindrical convex lens in an adjustable sliding mount to enable production of convergent, parallel or divergent beams. Complete with accessories which consist of: 5 Plastic blocks, one rectangular, One semicircular, One equilateral prism…
A simple kit that helps explain to students the principle of reflection and refraction. Using mirrors, lenses, acrylic prism sets, and a ray box, light can be reflected and refracted in different ways. The acrylic prism set includes a triangular, half-round, double convex, and rectangular prism and two double concave prisms all packed in a wooden storage box. A Newton…
A high-quality apparatus to determine precisely the co-efficient of expansion of various metals. An aluminum channel carries a 60 cm long metal rod enclosed in a heating jacket having three nipples for water intake, water outlet, and thermometer insertion. Dial indicator is a precision instrument sensitive to 0.01 mm/division and is securely mounted. As the apparatus works with hot water,…
Compact loupe magnifiers. Markings in both inches and centimeters for easy measuring. Fold flat for storing when not in use. Sturdy plastic frame. 1.25" x 7.8" when folded flat.
Understanding the principles of physics that occur on a roller coaster has become easier. This triple play apparatus consists of three tracks, one straight down, one with one loop, and the third with two loops. All three have different straight-up track lengths. At the end of each track is a catch sack to prevent losing the ball. The straight track…
To demonstrate the conservation of energy, conservation of momentum, and projectile motion. Consists of a metal track to drop a steel ball, and a circular scale for measuring the angle at which the ball drops. Includes two steel balls and instructions. Size: approx. 110 cm L.
The set consists of two plastic, 10cm-diameter hemispheres. Each half has a wooden handle firmly attached to it. One of the hemispheres has a raised edge to hold a rubber seal, while the other hemisphere has a stopcock for attaching to vacuum tubing. Join the hemispheres, hook them up to a vacuum pump, and evacuate the air inside the hemispheres.…
The transparent acrylic chamber contains iron filings. Chamber also has an internal tunnel into which a bar magnet can be inserted to demonstrate a magnetic field pattern. Other shaped magnets can be investigated by positioning their poles near one side of the chamber. With a Cylindrical magnet.
Consist of a closed transparent box with a transparent tube through the center. The box contains iron filings and silicon oil. When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and lined up along the field lines in all dimensions. With Cylindrical Magnet.
