Electromagnetic Waves question

2020 · 9 Jan · Shift 2 · Q62

JEE MainPhysicsElectromagnetic WavesMCQ+4 / −1
A plane electromagnetic wave is propagating along the direction i^+j^2{{\widehat i + \widehat j} \over {\sqrt 2 }}2​i+j​​, with its polarization along the direction k^\widehat kk . The correct form of the magnetic field of the wave would be (here B0 is an appropriate constant) :
  1. A
    B0i^−j^2cos⁡(ωt−ki^+j^2){B_0}{{\widehat i - \widehat j} \over {\sqrt 2 }}\cos \left( {\omega t - k{{\widehat i + \widehat j} \over {\sqrt 2 }}} \right)B0​2​i−j​​cos(ωt−k2​i+j​​)
  2. B
    B0i^+j^2cos⁡(ωt−ki^+j^2){B_0}{{\widehat i + \widehat j} \over {\sqrt 2 }}\cos \left( {\omega t - k{{\widehat i + \widehat j} \over {\sqrt 2 }}} \right)B0​2​i+j​​cos(ωt−k2​i+j​​)
  3. C
    B0j^−i^2cos⁡(ωt+ki^+j^2){B_0}{{\widehat j - \widehat i} \over {\sqrt 2 }}\cos \left( {\omega t + k{{\widehat i + \widehat j} \over {\sqrt 2 }}} \right)B0​2​j​−i​cos(ωt+k2​i+j​​)
  4. D
    B0k^cos⁡(ωt−ki^+j^2){B_0}\widehat k\cos \left( {\omega t - k{{\widehat i + \widehat j} \over {\sqrt 2 }}} \right)B0​kcos(ωt−k2​i+j​​)
