Tuning Fork Pair on box (Beats Apparatus)
It comprises two tuning forks each of frequency 426 Hz on two separate resonance boxes. One fork is fitted with adjustable loading mass. When both forks are sounded together, a clearly audible beat is produced. Rate of beats depends on difference in frequencies. This difference can be increased by changing the loading mass.

Van De Graff Generator
Van De Graff Generator for Physics Lab Hand operated on base. The generator is self exiting and charge separation occurs.
A metal sphere surrounds the upper pulley assembly and charge accumulates on the sphere, which is insulated by a plastic column supporting the pulley assembly. The charge builds up until electrical breakdown of air surrounding the sphere occurs, supplied with a discharging sphere.

Vibrator Electrical (Melde’s Apparatus)
This apparatus is an improvement over the conventional apparatus to show the effects of vibrations in a stretched cord and examine the relationship between frequency, tension and density. A thin steel rod is clamped near one end through two 4 mm socket terminals. This rod passes through the centre of a small solenoid and between the poles of a magnet. Adjustable contact points fitted through a second pair of 4 mm socket terminals make alternating connection with an adjustable contact on the rod. The rod has a small hole at one end for the attachment of thread which passes over a pulley mounted on a bench clamp and supports a scale pan, 75 mm diameter, supplied complete with pulley with clamp and scale pan, 2V A.C. power supply.
