A plane electromagnetic wave is propagagting along the direction `(hati+hatj)/(sqrt2),` with its poklarization along the direction `hatk.` The correct from of the magnetic field of the wave would be (here `B_(0)` is an appropriate constant):

Options

A. `(E_(o))/(C ) hatk`
`cos[10^(4) ((hati+hatj))/(sqrt(2)).vecr + (3 xx 10^(12)) t]`
B. `(E_(o))/(C ) ((hati - hatj))/(sqrt(2))`
`cos[10^(4) ((hati+hatj))/(sqrt(2)).vecr - (3 xx 10^(12)) t]`
C. `(E_(o))/(C ) ((hati + hatj + hatk))/(sqrt(3))`
`cos[10^(4)((hati + hatj))/(sqrt(2)).vecr +(3 xx 10^(12)) t]`
D. `(E_(o))/(C ) ((hati - hatj))/(sqrt(2))`
`cos[10^(4) ((hati - hatj))/(sqrt(2)).vecr - (3 xx 10^(12)) t]`

Answer

B
