Explain the term 'resistivity' and write its S. I . unit. Derive the expression for the resistivity of a conductor in terms of number density of free electrons and relaxation time.
Explain about the single mode fibres in intermodal dispersion. Into single mode fibers, the core size of the fibre is decreased to 3 to 9µm so that this supports simply axial m
Q Define threshold frequency? The minimum frequency of incident radiation lower which the photoelectric emission isn't possible completely but high the intensity of incident r
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
