Malus’s Law
Malus’s LawStudents can investigate the relationship between the proportion of transmitted light and the angle of rotation of two polarising filters. A graduated cartridge containing two polarising filters allows students to observe the change in intensity as they are rotated relative to one another.
Microwave Accessory Kit
Microwave Accessory KitComprising: 2 metal reflection/diffraction plates with base. Acrylic reflection/transmission plate with base 1 narrow metal plate to provide “Young’s Slits”
Microwave Complete Set TX, RX, RX, Probe
Microwave Complete Set TX, RX, RX, ProbeA set of all three Microwave units:
LA10-420 Microwave Transmitter
LA10-430 Microwave Receiver
LA10-440 Microwave Probe Detector
Microwave Polariser pair
Microwave Polariser pairA Pair of polarising grills for demonstrating the effects of polarisation with 3cm microwaves.
Microwave Probe Receiver
Microwave Probe ReceiverGives a localised, precision receiver which finds particular application in identifying areas of peak and low amplitude in interference, reflection and refraction experiments.
Microwave Receiver
Microwave ReceiverUses a plate antenna which gives high sensitivity over a broad area. Output is to an internal loudspeaker and power is derived from a mains plug-top unit (supplied).
Microwave Transmitter
Microwave TransmitterUtilizes a Schottky diode oscillator module feeding a tuned waveguide and horn to give a directional microwave beam. The beam is modulated with a variable frequency audio signal which can be adjusted by the control on the top panel.
Millisecond Timer
Millisecond TimerThe Lascells Millisecond Timer LA30-897 is a fully functional, easy to use millisecond timer and has a clear, 4 digit LED display.
Mini Loudspeaker 64ohm 0.5W
Mini Loudspeaker 64ohm 0.5WMini Loudspeaker 64Ω, 0.5W, 60mm dia. loudspeaker particularly suited to electronic circuits.
Mini Sonometer
Mini SonometerInstead of a one-off demonstration use the mini-sonometer to give your students hands-on experience of sound production.
The apparatus is constructed on an acrylic base with hardwood sides measuring 650 × 100mm overall. It has an integral pulley, wire clamp and half metre scale.
