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).
