Linear Polarizer (2-pack)Set of 2 linear polarizing sheets for classroom demonstrations.
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.
