Using B(0)=mu(0)H(0) formula find ratio ...

Using `B_(0)=mu_(0)H_(0)` formula find ratio of `(E_(0))/(H_(0))` for plane electromagnetic wave.

A

`(c )/(mu_(0))`

B

`mu_(0)c`

C

`(mu_(0))/(c )`

D

`mu_(0)c^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

`(E_(0))/(B_(0))=c` but `B_(0)=mu_(0)H_(0)`
`therefore (E_(0))/(mu_(0)H_(0))=c rArr (E_(0))/(H_(0))= mu_(0)c`
