A plane electromagnetic wave E_(z) = 100 "cos" (6xx10^(8)t +4x) V/m propagating in medium of dielectric constant is

A place electromagnetic wave E_z = 100 cos(4 \times10^-7 z - 50 t) V/m propagates in a medium. Find the refractive index of the medium.

Electric field of one plane progresive electromagnetic wave is E_(Z)=100 cos (6xx10^(8)t + 4x)Vm^(-1) . Then refreactive index of medium pf propagation would be …..

A plane electromagnetic wave propagates in a medium moving with constant velocity Vlt lt c relative to an interial frame K . Find the velocity of that wave in the frame K if the refractive index of the medium is equal to n and the propagation direction of the wave coincides with that of the medium.
