Hook Weight Set
Set consists of seven polished brass weights and two black enameled weights with flat countersunk bottoms. Each weight is accurately adjusted and the value clearly indicated. Individual masses are as follows: 1 x 10 gm, 2 x 20 gm, 1 x 50 gm, 1 x 100 gm, 2 x 200 gm, 1 x 500 gm, 1 x 1000 gm.
Pendulum Demonstration
This setup clearly demonstrates simple harmonic motion and the conservation of energy. In simple harmonic motion, pendulum swings evenly from side to side. Use photogate timer to accurately measure the period of the pendulum or the speed of the pendulum bob at the bottom of the swing. The length of the string can be adjusted to measure the change in period. Also see the effect of change in mass on the period. Two pendulum bobs are provided. Photogate Timer is not included.
Adjustable Pendulum
This is a double pendulum apparatus to investigate the fundamental properties of pendulum. The length of the pendulum can be varied using the steel balls to observe the effects. It can be mounted to any retort stand upto 13 mm rod diameter. Two steel balls are provided with the apparatus. With this apparatus, the qualitative studies of periods of steel balls with individual string lengths, frequency and beats can be done. A stopwatch is required to examine these ideas quantitatively. User instructions are provided.
Magdeburg Pressure Disks
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. You will find it hard to pull them apart. Open the stopcock to let air in and the hemispheres will separate easily.
Wind Power Demonstrator
This wind power generator can be used to demonstrate the generation of electricity by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small LED and a voltmeter. Instructions included.
Size of Particle Experiment
OBJECTIVES
PRINCIPLE
The characteristics of light such as interference and diffraction can be understood when light is studied as a wave phenomenon. Interaction of waves with matter results in either transmission, reflection, absorption, or diffraction of the wave. When the size of the matter is comparable to the wavelength of the wave that it interacts with, a phenomenon called diffraction occurs. Diffraction of light due to particles is a function of the size of the particle and the wavelength of the light incident. It is possible to measure the size of a particle by studying the diffraction patterns created by it.
