Acylic Hammer for Tuning fork

Made of Acrylic
Acrylic Hammer for Tuning Fork

Bell in Vacuum Sound Jar

This is an integral system with the pump plate & hand vacuum pump. The plate comes with a rubber seal which facilitates sealing in bell jar experiments. The plate can be used with electric vacuum pumps also. A rubber seal is provided for copper pump plate.
• Copper plate with rubber seal
• Hand vacuum pump
A new improved Acrylic Bell Jar of size 25 x 14 cm compatible with the pump plate. The bottom flange is ground flat to ensure a perfect seal. Electric bell is mounted for sound in vacuum experiments. Operates on 4-6V AC/DC.

Doppler Effect Apparatus

• A simple yet educational tool.
• The Doppler Apparatus is a fantastic tool to demonstrate the concept of the Doppler Effect and stimulate student curiosity.
• Simply tie the rope around the apparatus, turn it on and swing it around in circles.
• The change in pitch as the apparatus rotates in circles is easily recognizable.
• The manual comes with a theoretical section on the Doppler Effect, instructions about how to perform the demonstration and a STEM section explaining practical real-world applications of the Doppler Effect.
• 48 inches of rope is supplied with each apparatus

Forced Oscillation & Resonance Demonstrator

Designed to show the vibration of an object when repeated impulses are applied, this demonstrator consists of two weights of different natural frequencies, two cams driven by a 6V motor with speed control, and four springs. The speed control is used to adjust the frequency of applied force for resonance, so a greater degree of variance is possible. Includes an instruction manual. Size 30 x 15 x 45 cm

Organ Pipe

Polished wood, with movable piston marked with the chromatic scale from C (512) to (1024). Overall length when fully extended 880 mm May be used for investing the phenomenon of beats in conjunction with a second pipe of the same type.

Resonance Apparatus

Acrylic tube approx. 98 cm long and 2.5 cm diameter mounted on retort stand with clamp and boss, with metal vessel, connecting tubing and spring clip supported on iron ring.

Ripple Tank Apparatus

To illustrate important wave motions like rectilinear and circular motion. This Ripple Tank is comprised of a molded frame with an acrylic window. Scratch resistant supported by adjustable legs. This dual purpose tank is a versatile apparatus allowing all types of waves and wave motion. With illuminator lamp and important accessories included it forms a complete ready to use unit save for a Ripple Tank Controller. The unique design and size allows it to be used on an overhead projector as well.

Sonometer

Comprising a wooden baseboard 98 x 9 cm mounted on four feet. At one end of the base are two 50N. spring balances with hooks, and at the other end are two corresponding wrest pins. Also provided are three bridges, one large to span both wires and two small for the individual wires. Supplied with two steel wires of 30 SWG one meter long.

Tuning Fork Electric

Heavy-duty electric tuning fork. An electromagnet drives the fork to a sustained frequency of 80Hz. The tuning fork assembly and binding posts are mounted on a stable cast-metal base.
To show relationships between frequency, length, tension and mass or learn about Melde’s standing wave experiments with this heavy duty electric tuning fork. An electromagnet drives the fork to a sustained frequency of approx. 80Hz. One prong of the tuning fork has a captive knurled thumbscrew for performing Melde’s experiment. Amplitude of the tuning fork vibrations is varied by means of a threaded adjustment screw. Universal binding posts are finished to provide electrical power from an external source of 2 to 6 volts DC.

Tuning Fork on Resonance Box

Wave Apparatus Metal

This advanced apparatus demonstrates both longitudinal and transverse wave motions. Consisting of a number of eccentric discs supporting a series of metal rods revolving on a handle, transverse waves are obtained. Longitudinal waves are obtained from the bent rods.

Wave Apparatus Plastic

Wave form Helix 10cm closed height

This is a Wave Form Helix that can be:
1) used as a scientific instrument to measure a wave function (it actually has a higher spring constant than the classic toy); or
2) unleashed down a wicked set of stairs.
It has a 7.5 cm diameter, 10 cm long when closed, and up to 3 meters in length when fully stretched.
