Question : 1

Total: 51

The electric field in a plane electromagnetic wave is given by
Ez=60‌cos(5x+1.5×109t)‌V∕m
Then expression for the corresponding magnetic field is (here subscripts denote the direction of the field) :

Bz=60‌cos(5x+1.5×109t)‌T
By=60sin‌(5x+1.5×109t)T
By=2×10−7‌cos(5x+1.5×109t)‌T
Bx=2×10−7‌cos(5x+1.5×109t)‌T
