Read the following passage and then answer questions (a) to (e) on the basis of your under- standing of the passage and the related studied concepts. In accordance with Faraday.s law of electromagnetic induction a magnetic field, changing with time, gives rise to an electric field. Again as per Ampere-Maxwell.s law an electric field, changing with time, gives rise to a magnetic field. It means that if we consider a charge oscillating with some frequency, it produces an oscillating electric field in space, which produces an oscillating mag- netic field, which in turn, is a source of oscillating electric field and so on. The oscillating electric and magnetic fields thus regenerate each other and an electromagnetic wave propagates through space. The energy associated with the propagating wave comes at the expense of the energy of the oscillating charge. Electromagnetic wave propagates through free space as a transverse wave in which vecE and vecB are perpendicular to each other as well as perpendicular to the direction of wave propagation. Like other waves electromagnetic waves carry energy and momentum. As electromagnetic waves contains both electric and magnetic fields, it has an electrical energy density mu_(E)=(1)/(2)in_(0)E^(2) as well as a magnetic energy density mu_(B)=(B^(2))/(2mu_(0)). Both of these vary with time. What is the frequency and wavelength of the electromagnetic wave?
