The magnetic field in a plane electromagnetic wave is given by B_(y) = 2 xx 10^(-7) sin (0.5 xx 10^(3)x + 1.5 xx 10^(11) t) . This electromagnetic wave is

For a plane electromagnetic wave, the magnetic field at a point x and time t is vec(B) (x,t) = [1.2 xx 10^(-7) sin (0.5 xx 10^3x + 1.5 xx 10^11t)hatk]T The instantaneous electric field vecE corresponding to vecB is : (spped of light c = 3 xx 10^8 ms^(-1) )

The magnetic field in a plane electromagnetic wave is given by vecB=2×10^-7 [sin(0.5×10^3x+1.5×10^(11)t)hatj] . The electric field is given by (where B is in T , x is in m and t in s)
