55779 Experimental Set-Up has been designed specifically for experiments with Sonometer.
(1) To determine the frequency of a tuning fork.
(2) To verify the laws of vibrating strings.
(3) To determine the frequency of AC mains using horse shoe magnet and non magnetic wire.
(4) To determine the frequency of AC mains using electromagnet & magnetic wire. The set up consists of Tuning forks, Sonometer with Steel and Brass wires, Electromagnet, Horse shoe magnet, ½ kg weights, Retord stand with clamp, Step down transformer, Screw gauge etc. Practical experience on this set up carries great educative value for Science and Engineering Students.
