Question

A plane electromagnetic wave in a non magnetic dielectric medium is given by Ē = Ēo(4 x 10-7-590)
[2013]
with distance being in meter and time in seconds. The dielectric constant of the medium is:​

Answer 1

Explanation:

A plane electromagnetic wave in a non magnetic dielectric medium is given by E=E°(4×10^(-7)x-50t) with distance in meters and time in seconds.

V=w/k

Thus,v=12.5×10^-7

Dielectric constant k=c/v

Where c is speed of light

Thus ans is 2.4 option
