A plane electromagnetic wave in a non-magnetic dielectric medium is given by vecE = vecE_(0)(4 xx 10^(-7) x - 50 t) with distance being in meter and time in seconds. The dielectric constant of the medium is :

A plane electromagnetic wave propagating in a non-magnetic dielectric medium is given by E=E_(0)[4 times 10^(-7)x-50t] , where x is in metre and t is in second. If the relative permeability of the medium, mu_(r)=1 then the dielectric constant of the medium is

The velocity of light in a medium is 2 xx 10^8 ms^-1 . The refractive index of the medium is

An electromagnetic wave travelling through a transparent medium is given by E_(x)(y,t)=E_(ax)sin2pi[y/(5xx10^(-7))-3xx10^(14)t] in SI unit then the refractive index of medium is,

An electromagnetic wave travelling through a transparent medium is given by E_(x)(y,t)=E_(ax)sin2pi[y/(5xx10^(-7))-3xx10^(14)t] in SI unit then the refractive index of medium 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.

If the velocity of light in a medium is 2.25 xx 10^(8) ms^(-1) then the refractive index of the medium will be
