Linear Translator
Linear TranslatorUsed with the Rotary Motion Sensor and provides position data to the computer. Can be attached to Basic Optics Bench.
Longitudinal Wave Spring
Longitudinal Wave SpringDemonstrate and visualize nodes and antinodes of longitudinal waves.
Loop-the-Loop
Loop-the-LoopHow high do you have to start the ball to make it go over the loop? Students use Conservation of Energy to determine how much potential energy is needed to have enough speed to make it around the loop.
Lost Volts
Lost VoltsThis ‘Lost Volts’ apparatus provides a convenient solution for experimentally determining the internal resistance and the EMF of a cell.
The unit requires connection to a 6V DC source of EMF, a voltmeter and an ammeter.
Lost Volts Separates
Lost Volts SeparatesA pack of 5 convenient and appropriately rated mounted components to enable students to carry out an experiment to determine the EMF and internal resistance of a cell.
Loudspeaker on rod, 3 W
Loudspeaker on rod, 3 WUsed with function generator FR-250350 or FR-250310 to generate sound from a point source. With two speakers you can demonstrate interference.
Low Voltage AC/DC Power Supply
Low Voltage AC/DC Power SupplyThis rugged, general purpose supply, provides the voltages most commonly needed with plenty of current for almost any experiment.
Magdeburg Plates
Magdeburg PlatesThese two plates are a modern and versatile rendition of a classic vacuum demonstration.
