Question
In long range transmission, why micro waves are better carrier than radio waves?

Answer

In long range transmission, micro waves are better carrier than radio waves because their wavelength is very less as compared to radio waves. Due to this, during obstruction, they suffer minimum deviation and can be sent directly towards the aim.

When a semiconducting material is doped with an impurity, new acceptor levels are created. In a particular thermal collision, a valence electron receives an energy equal to 2kT and just reaches one of the acceptor levels. Assuming that the energy of the electron was at the top edge of the valence band and that the temperature T is equal to 300K, find the energy of the acceptor levels above the valence band.
