Pumping is the process to achieve population inversion .
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
In 1895, German physicist Wilhelm Roentgen discovered X-rays. X-rays are electromagnetic in nature and application of X-rays are innumerable.
A predictable correlation of the amplitude and phase at any one point with another point is called coherence.
Maxwell’s equations explain the unique co-occurrence of the electric field and the magnetic field.
Faraday’s law gives the idea about how an electromotive force comes into action when a magnetic field interacts with an electric circuit.
Rate of Stimulated emission depends upon the number of atoms present in the excited state as well as the energy density of photons.
Simple Harmonic Motion (SHM) is when the restoring force is directly proportional to the displacement of the body from its mean position.
Plasticity is the property of the material by virtue of which it does not regain its original shape when applied force is removed.
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).
Drude and Lorentz gave classical free electron theory of metals theory in 1900. Another name for this is Drude –Lorentz theory of metals.
The materials which exhibit this property of superconductivity are known as Superconductors.
