Define electromagnetic wave.

Statement I: The electric field vecE and the magnetic field vecB are mutually perpendicular at a point in the electromagnetic wave. Statement II: Electromagnetic waves are transverse waves.

When the electromagnetic wave enters into a medium from free space, (A) Velocity of the wave decreases (B) Frequency of the wave decreases (C) Wavelength of the wave decreases (D) Frequency increase and wavelength decreases

Statement I: The ratio of the amplitudes of electric and magnetic fields at a point in the electromagnetic wave is same as the velocity of wave. Statement II: If in a medium, mu and in are the magnetic permeability and the electric permittivity respectively, then 1//sqrt(muin) is the velocity of electromagnetic wave in that medium.

The ratio between the amplitudes of electric and magnetic fields at any point on a progressive electromagnetic wave in free space is equal to
