Harmonic Motion and Waves Virtual Lab

Harmonic Motion and Wave lab is the interdisciplinary science that deals with the study of sound, ultrasound and infrasound (all mechanical waves in gases, liquids, and solids). The study of this lab revolves around the generation, propagation and reception of mechanical waves and vibrations.

Astable multivibrator
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
Ultrasonic Interferometer is a device used to calculate the velocity of ultrasonic sound through different liquid media.
Doppler Effect
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.
A.C Sonometer
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
Colpitts Oscillator
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
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.
