Physics

According to the De-Broglie concept, with each moving particle a wave is associated.

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

Walter Meissner and Robert Ochsenfeld discovered a magnetic phenomenon in 1933. He studied and give the Meissner effect.

The materials which exhibit this property of superconductivity are known as Superconductors.

Maxwell’s equations explain the unique co-occurrence of the electric field and the magnetic field.

Diffraction can be defined as bending of light when it passes around the edge of an object.

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

Compton discovered the most important confirmation about the particle aspect of radiation.

The effect of magnetic field on the atomic spectral lines is known as Zeeman Effect.

P-N junction diode is simply a two-terminal device which allows the current to flow in one direction only.

The phenomenon of Raman scattering of light was experimentally observed in 1928 by Raman and Krishnan.

The process of converting unpolarized light into polarized light is known as polarization.

A predictable correlation of the amplitude and phase at any one point with another point is called coherence.

Semiconductors are materials that have conductivity between conductors and insulators.

LASER stands for “Light Amplification by Stimulated Emission of Radiation”.

A cable that is used to transmit the data through fibres (threads) or plastic (glass) is known as an optical fibre cable.

Heisenberg’s uncertainty principle states that: If the x-component of the momentum of a particle is measured with an uncertainty ∆px, then its x-position cannot, at the same time, be measured more accurately than ∆x = ℏ/(2∆px).
