Magnetic field in a plane electromagnetic wave is given by
`bar(B) = B_(0)"sin"(kx + omegat)hat(j)T`
Expression for corresponding electric field will be

A

`vecE=B_(0)c sin(kx+omegat)hatkV//m`

B

`vecE-(B_(0))/(c)sin(kx+omegat)hatkV//m`

C

`vecE=-B_(0)c sin (kx+omegat)hatkV//m`

D

`vecE=B_(0)c sin (kx-omegat)hatkV//m`

Text Solution

Verified by Experts

The correct Answer is:
A
Speed of EM wave in force space `(c )=(E_(0))/(B_(0))`
or `vecE=c B_(0)sin (kx+omegat)hatk`
