The wave function contains all the information about the particle. It is not an observable quantity.

Plasticity is the property of the material by virtue of which it does not regain its original shape when applied force is removed.

The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).

Magnetic Hysteresis Curve represents the relation between magnetizing force (H) and magnetic flux intensity for ferromagnetic material.

Simple Harmonic Motion (SHM) is when the restoring force is directly proportional to the displacement of the body from its mean position.

Semiconductors are materials that have conductivity between conductors and insulators.

W. L. Bragg gave a simple explanation for the study of crystal structure by using the phenomenon of diffraction and name it is as Bragg’s law.

Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.

Interference of waves occurs when two or more waves overlap at a given point.
