Design and set up an astable multivibrator and calculate the time period and duty cycle of the output wave form.
|Melde's String Apparatus|
Aim is to determine the frequency of electrically maintained tuning fork.
|Kundt's Tube Apparatus|
Kundt's tube is a device used to calculate the velocity of sound through a metal rod. Also the Young's modulus of the rod can be calculated.
Ultrasonic Interferometer is a device used to calculate the velocity of ultrasonic sound through different liquid media.
The Doppler Effect is the perceived change in frequency of sound emitted by a source moving relative to the observer.The effect was first noted by Christian Doppler in 1842.
Every object has a natural frequency of vibration. If kinetic energy is applied to an object at a rate that matches its natural frequency, resonance occurs and the object vibrates. In this experiment a small current, produced by a signal generator, causes
A Colpitts oscillator, invented in 1920 by American engineer Edwin H. Colpitts, is one of a number of designs for electronic oscillator circuits using the combination of an one inductance (L) with two capacitor (C1,C2) for frequency determination.
Hartley Oscillator is an electronic oscillator,which uses two inductor and a capacitor to determine frequency.It is high frequency generator.Invented in 1915 by American engineer Ralph Hartley.
