Answer the following questions related to the basic quantities of a plane electromagnetic wave.
(i) Define the amplitude of the electric field and the amplitude of the magnetic field in a plane electromagnetic wave.
(ii) State the relation between the peak values of the electric and magnetic fields in a plane electromagnetic wave travelling in free space.
(iii) State the expression that relates the speed of an electromagnetic wave in free space with the fundamental constants of vacuum permeability and vacuum permittivity, clearly naming these constants.
(iv) Write the accepted value of the speed of light in vacuum in SI units.
