Relation of amplitude of corelate of electric and magnetic field is ……..

Options

A. (A)`E_(0)=B_(0)`
B. (B) `E_(0)=cB_(0)`
C. (C) `E_(0)=(B_(0))/(c )`
D. (D) `E_(0)=(c )/(B_(0))`

Answer

B

Explanation

From the characteristic of electromagnetic wave relation between `vec(E )` and `vec(B)` is `(E )/(B)=c`
Putting `|vec(E )|=E_(0)sin(omega t-kx)` and
`|vec(B)|=B_(0)sin(omega t-kx)`
`(E_(0))/(B_(0))=c`
`therefore E_(0)=cB_(0)`
