A plane electromagnetic wave propagating...

A plane electromagnetic wave propagating along y-direction can have the following pair of electric field `(vecE)` and magnetic field `(vecB)` components.

`vecE = (vecnxx vecB)/c`

`vecB = (vecnxx vecE)/c`

`vecE = -chatn xx vecB`

`hatn xxvecE xx vecB =0`

Text Solution

Verified by Experts

The correct Answer is:

Direction of propagation is given by `vecE xx vecB`
i.e. `hatn = hatExxhatB` and speed of light `(c) = E/B`
Hence, option (a) is wrong.
