If E _ O and B _ o are the magnitudes of the electric and magnetic fields respectively of an electromagnetic wave in vacuum, then among the following the correct relation is ( ₀- permeability of free space, ₀- permittivity of free space)
Options
- AE_o=B_o _o _o
- BE _ o _ o = B _ o _ o
- CE _ o _ o = B _ o _ o
- DE _ o _ o = B _ o _ o
Correct answer
C. E _ o _ o = B _ o _ o
Step-by-step solution
Speed of light is given as: gathered E_o=c B_o c= E_o B_o gathered According to maxwell speed of light is given as aligned & c= 1 ₀ ₀ & E_o B_o = 1 _o ₀ & E_o ₀ = B_o _o aligned
