Electromagnetic Waves question

2025 · 23 Jan · Shift 2 · Q52

JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
A plane electromagnetic wave of frequency 20 MHz travels in free space along the +x+x+x direction. At a particular point in space and time, the electric field vector of the wave is Ey=9.3Vm−1\mathrm{E}_y=9.3 \mathrm{Vm}^{-1}Ey​=9.3Vm−1. Then, the magnetic field vector of the wave at that point is
  1. A
    Bz=1.55×10−8 T\mathrm{B}_z=1.55 \times 10^{-8} \mathrm{~T}Bz​=1.55×10−8 T
  2. B
    Bz=6.2×10−8 T\mathrm{B}_z=6.2 \times 10^{-8} \mathrm{~T}Bz​=6.2×10−8 T
  3. C
    Bz=3.1×10−8 T\mathrm{B}_z=3.1 \times 10^{-8} \mathrm{~T}Bz​=3.1×10−8 T
  4. D
    Bz=9.3×10−8 T\mathrm{B}_z=9.3 \times 10^{-8} \mathrm{~T}Bz​=9.3×10−8 T
