Electromagnetic Waves question

2018 · 15 Apr · Shift 2 · Q46

JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
A plane polarized monochromatic EM wave is traveling in vacuum along z direction such that at t = t1 it is found that the electric field is zero at a spatial point z1. The next zero that occurs in its neighbourhood is at z2. The frequency of the electroagnetic wave is :
  1. A
    3×108∣z2−z1∣{{3 \times {{10}^8}} \over {\left| {{z_2} - {z_1}} \right|}}∣z2​−z1​∣3×108​
  2. B
    1.5×108∣z2−z1∣{{1.5 \times {{10}^8}} \over {\left| {{z_2} - {z_1}} \right|}}∣z2​−z1​∣1.5×108​
  3. C
    6×108∣z2−z1∣{{6 \times {{10}^8}} \over {\left| {{z_2} - {z_1}} \right|}}∣z2​−z1​∣6×108​
