A) Gauss's law of magnetism is given by \[\oint{B.ds=0}\]
B) An EM wave is a wave radiated by a charge at rest and propagates through electric field only
C) A time varying electric field is a source of changing magnetic field
D) Faraday's law of EM induction is \[\oint{E.dl=-\frac{d{{\phi }_{B}}}{dt}}\]
Correct Answer: C
Solution :
An electromagnetic wave is that type of wave which is radiated by an accelerated charge and which propagates through space as coupled , electric and magnetic field. These fields are oscillating perpendicular to each other. Hence, the option (c) is wrong.
