Given below are two statements:
Statement I: A time varying electric field is a source of changing magnetic field and vice-versa. Thus a disturbance in electric or magnetic field creates EM waves.
Statement II : In a material medium, the EM wave travels with speed 
.
In the light of the above statements, choose the correct answer from the options given below.
Text Solution
Verified by ExpertsThe correct answer is:
C
In a material medium, speed of EM wave is, 
where µ and ε are permeability and permittivity of the medium.
. So, statement II is false.
