Alloying: When an impurity atom of a different size compared to the host atom is placed into the crystal lattice, the impurity atom distorts the resin around it, either by pushing the host atoms farther away, or by pulling them in, as depicted. The cross section that scatters the electron is the lattice region that has been elasticity distorted by the impurity (the impurity atom itself and its neighbouring host atoms), so that in this zone, the electron suddenly experiences a force due to sudden change in PE. This region has a large scattering event from impurity only. We define τt as the mean time between scattering events arising from thermal vibrations alone and as the mean time between scatterings events arising from collisions with impurity alone. In, general an electron may be scattered by both processes, so effective mean time τ between any which scattering events will be less than the individual scattering time.
IF a football player kicks a football so that it spends 3.0 seconds in the air and travels 50m, then find the velocity and angle of the kick.

Explain about the term spatial coherence of Laser. Spatial coherence: This coherence is a measure of the correlation among the phases of a light wave at several points’ tran
what is the mass of CPH? Answer; Since I told before, when CPH takes spin it calls graviton. Thus, our problem is the mass of graviton. There isn't any acceptable summa.
