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 v=1μ0∈0v = {1 \over {\sqrt {{\mu _0}{ \in _0}} }} . In the light of the above statements, choose the correct answer from the options given below.

Multiple Choice Options

  • A Both Statement I and Statement II are true
  • B Both Statement I and Statement II are false
  • C Statement I is correct but Statement II is false
  • D Statement I is incorrect but Statement II is true

Step-by-Step Verified Solution

In a material medium speed of light is given by v=1ε0εrμ0μrv = {1 \over {\sqrt {{\varepsilon _0}{\varepsilon _r}{\mu _0}{\mu _r}} }} . So statement 2 is false.
