Question

Electric field in a travelling electromagnetic wave has a peak value of 6 v/m. The peak value of magnetic field. Strength is :

Answer 1

The peak value of magnetic field strength is 2.8 X$10^{-8}$ T

Explanation:

        E = 6 V/m

we know that  $E_{rms}$/$B_{rms}$ = c

where $E_{rms}$ = Electric field

           $B_{rms}$ = Magnetic field

     and c = speed of light

  $B_{rms}$ = $\frac{6}{3 X 10^{-8} }$ = $2 X 10^{-8} T$

     since , $B_{rms} = \frac{B_{0} }{\sqrt{2} }$

                 $2 X 10^{-8} X\sqrt{2}$

                = 2.8 X$10^{-8}$ T
