Velocity of electromagnetic waves in a medium is ..

If velocity of an electromagnetic wave in a medium is 3 x10^(8) m/s then find refractive index of medium.

The velocity of an electromagnetic wave in a medium is 2xx10^(8) mS^(-1) . If the relative permeability is 1 the relative permittivity of the medium is (C_(0)=3xx10^(8) mS^(-1))

Velocity of electromagnetic waves in a medium depends upon

Electric field in plane electromagnetic wave is given by E=50sin(500x-10xx10^(10)t)V//m The velocity of electromagnetic wave in this medium is : (Given C= speed of light in vacuum)

The electromagnetic waves

Write down the expression for the velocity of electromagnetic wave in a medium and hence find out an expression for the refractive index of the medium.

In an electromagnetic wave

Electromagnetic waves are

The velocity of electromagnetic waves in a dielectric medium (in_(r)=4) is
