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 $\displaystyle v=\frac{1}{\sqrt{\mu_0 \epsilon_0}}$.
In the light of the above statements, choose the correct answer from the options given below.
Official answer
(3)
Statement I is correct but statement II is false
