A plane electromagnetic wave having a frequency v = 23.9 GHz propagates along the positive z-direction in free space. The peak value of the electric field is 60 {V /m. which among the following is the acceptable magnetic field component in the electromagnetic wave ? [12 Apr 2019 Shift 2]

Correct Answer is : →B=2×10−7sin (0.5×103z−1.5×1011t )^i

B^{\to}=2 \times 10^{-7} \sin (0.5 \\times10^{3} {z}-1.5 \times 10^{11} t ) i^{\^}

B^{\to}=2 \times 10^{-7} \sin (0.5 \\times10^{2} {x}-1.5 \times 10^{11} t ) i^{\^}

B^{\to}=2 \times 10^{-7} \sin (0.5 \\times10 ^{3}z-1.5 \times 10^{11} t ) i^{\^}

B^{\to}=60 \sin (0.5 \\times10 ^{3}z-1.5 \times 10^{11} t ) i^{\^}
