Lattice dynamics is an essential component of any postgraduate course in Physics, Engineering Physics, Electronic Engineering and Material Science. In particular it is essential for understanding the interaction of electromagnetic waves and crystalline solids. In...

To measure the Curie temperature of a body where the body losses its ferromagnetic property and changes to a paramagnetic state if it is further heated. An inductor with Ferrite core [ sample] connected to an ac source along eith a resistor . The sample keep on the...

A CRT is a linear particle accelerator that creates an image on a fluorescent screen by accelerating and deflecting a beam of electrons in a vacuum. The following experiments to be done :  Producing the free Particles.Deflecting an Electron beam with an Electrostatic...

Conversion of Vibration to Voltage using Piezoelectric materials Many electronic devices today use piezoelectricity. For example, when you use some type of voice-recognition software, or even on your smartphone, the microphone that you’re speaking into is...

To study the Conversion of thermal energy into voltage using thermoelectric modules. Solid-state thermoelectric devices are at present used in verity of applications ranging from thermocouple sensors to power generators in satellites, to handy air-conditioners and...

This experiment measures e/m, the charge to mass ratio of the electron. In the present experiment a beam of electrons is accelerated through a known potential, so the velocity of the electrons is known. A solenoid  produces a uniform and measurable magnetic field...
