When a P-type semiconductor is suitably joined to an N-type semiconductor, then resulting arrangement is called P-N junction or P-N junction diode
Depletion region: On account of difference in concentration of charge carrier in the two sections of P-N junction, the electrons from N-region diffuse by the junction into P-region and the hole from P region diffuse into N-region.
Because of diffusion, neutrality of both N and P-type semiconductor is disturbed, a layer of negative charged ions appear near the junction in the P-crystal and a layer of positive ions appears by the junction in N-crystal. This layer is known as depletion layer
The phenomenon of diffraction was first discovered by Girmaldi. Its experimental study was completed by Newton's and young. The theoretical explanation was first provided by Fresne

As an electron passes close to the positive nucleus of atom, the electron is moved from its path as given in diagram. This results in deceleration of the electron. The loss in powe

What is Centrifugal Force? Centrifugal force is the force that is equivalent in magnitude but opposite in direction to the centripetal force, which is the force directed toward
the sun warming the earth is an example of?
What do you mean by lateral shift? Derive a mathematical expression for lateral shift produced by a parallel sided glass slab for oblique incidence.
Is CPH a quantum energy unchangeable? Answer- Yes, the quantum energy (photon) is made of lots CPH, different between photons depend to the number of CPH that they are made of.
