  • In a plane electromagnetic wave the electric field oscillates sinusoidally at a frequency

In a plane electromagnetic wave the electric field oscillates sinusoidally at a frequency 2\times 10^{10}Hz and amplitude 48\frac{v}{m}. The amplitude of oscillating magnetic field will be?

Answers (1)

Relation between Eo and Bo -

E_{o}=c.B_{o}

- wherein

E_{o}= Electric field amplitude

B_{o} = Magnetic field amplitude

C= Speed of light in vacuum

 

 Oscillating mag. field

B=\frac{E}{C}= \frac{48}{3\times 10^{8}}= 16\times 10^{-8}
