What is spontaneous emission? Explain in brief.
Spontaneous emission:
a. This is the process by that a light source as like an atom, molecule, nano-crystal or nucleus into an excited state undergoes a transition to the ground state and then emits a photon.
b. The atoms into the excited state drop to the lower energy state after they have stayed within the excited state for a short duration of time known their life time.
c. Throughout this process photons of energy hν = E2 - E1, that is energy difference in between the two states of the atom, those are emitted.
d. Spontaneous emission of light or luminescence is a basic process which plays a necessary role in various phenomena into nature and forms the basis of several applications, as like fluorescent tubes, plasma display panels, television screens, lasers and light emitting diodes.
STATOR: It is made up of a number of stampings which are slotted to be given windings. The stator carries 3φ windings and is fed from 3φ supply. It will be for a exact number of
In general the total energy of a harmonic oscillator having of two parts, potential energy (P.E) and kinetic energy (K.E.), the former being because of its displacement from the m

Q. A twelve-slit strobe disc is rotated at the max stopping frequency for a vibrating object. The strobe is rotated at 4.0 Hz. (a) Evaluate the period of the vibrating object?
As a longitudinal wave moves through a medium, the particles of the medium: a) vibrate in a path parallel to the path of the wave b) vibrate in a path perpendicular to the p
Q Define: mobility. Give its unit. The mobility is defined as the drift velocity obtains per unit electric field. The unit of a mobility m 2 V 1s 1.
Explain displacement x(t) is known as displacement and it denotes the position of a body at time. If the displacement is positive then that body is to the right of the chosen
