Physics
Speed of Light
Very short but powerful pulses of light are emitted from the box. When the light pulses hit the special retroflective foil of the reflector they are directed back towards the source – with no need for tedious adjustments. Via a beamsplitter, the light pulses finally hit a high speed photodiode, converting them into electric pulses to be displayed on an oscilloscope. A separate synchronization signal marks the time of pulse emission and constitutes a reference for timing the pulses.

Speed of Sound
This is an easy to use piece of apparatus for determining the speed of sound in air.
The unit contains two sensitive microphones connected to control circuity that will start and stop a Lascells millisecond or microsecond timer. Alternatively the outputs may be monitored on a storage or pc oscilloscope.SKU: LA50-560 -

Splat The Rat
Fun and dramatic demonstration of Lenz’s Law. Interactive and entertaining demonstration of induced currents and magnetic fields. Lenz’s Law can be demonstrated using the standard Eddy Current Tubes whereby a magnet falls through a copper tube at a slower rate than an un-magnetised weight.
