Question

In an electromagnetic wave in free space the root mean square value of the electric field is Erms = 6 V/m The peak value of the magnetic field is​

Answer 1

$\huge\red[A]\pink[N]\orange[S]\green[W]\blue[E]\gray[R]$

Erms=6V/m

Erms=Erms×2=62V/m

Now, E=CB

→B=CE=3×10862

=2.25×10−8T

=2.828×10−8T
