Given below are two statements :
Statement I: A time varying electric field is a
\( \mathrm{P} \)
source of changing magnetic field and vice-versa.
W
Thus a disturbance in electric or magnetic field creates EM waves.

Statement II: In a material medium, the EM wave travels with speed \( v=\frac{1}{\sqrt{\mu_{0} \varepsilon_{0}}} \).

In the light of the above statements, choose the correct answer from the options given below :
(1) Both statement I and statement II are true.
(2) Both statement I and statement II are false.
(3) Statement I is correct but statement II is false.
(4) Statement I is incorrect but statement II is true.
