The direction of electromagnetic wave is in the direction of

Options

A. (A) `(vec(E ))/(vec(B))`
B. (B) `vec(E )xx vec(B)`
C. (C) `vec(B)xx vec(E )`
D. (D) `vec(B)`

Answer

B

Explanation

Taking the direction in consideration in the phenomenon of propagation of electromagnetic waves, `vec(E )_|_ vec(B)_|_ vec(v)` from the right hand screw rule.
`vec(E )xx vec(B)_|_ vec(v)`
`therefore` It becomes `vec(E )xx vec(B)= vec(v)`
