Description :-
For measuring the resonant length of an air column driven by a tuning fork.
Comprises a brass tube 292 x 27 mm diameter fixed to a base with a sliding inner tube 305 mm long which allows the length of the air column to be varied from 350 to 530 mm.
Description :-
Stroboscopic flashes are triggered by either the internal oscillator or by external pulses which may be connected to the two 4mm sockets mounted on the rear panel of the instrument. Example of the many applications of this unit are to be found in motion analysis multi exposures photography, examination of moving parts and measurement of rotational speed.
Specifications:-
Input Volts : 220V AC, 50 Hz
Flash Rate: 0- 9999 Flashes per minute.
Resolution : 1
Display: 7 Segment LED (4 nos.)
Description :-
Demonstrating longitudinal and transverse waves.
A number of eccentric discs move a number of metal rods.
Transverse waves are obtained by straight rods and longitudinal waves by bent rods.
Description :-
On sturdy base, can be used in horizontal or vertical position. Prong size is 300 x 25 x 10 mm. Actuated by an electromagnet between the prongs, works with 6 V D.C. Amplitude of vibration can be varied by adjusting the position of the electromagnet.
Description :-
Tuning Fork Activator is used as a surface to gently strike the tuning fork to activate vibrations.
Rubber activator is tapered so the bottom is wider for stability.
Made of solid rubber.
