Question

A planar electromagnetic wave is propagating in the +x direction. At a certain point P and at a given instant, the electric field of the wave is given by = (0.082 V/m) . What is the magnetic vector of the wave at the point P at that instant? (c = 3.0 × 108 m/s)

    Answer:

    B=2.74\times 10^{-10}\ T

    Explanation:

    It is given that,

    A planar electromagnetic wave is propagating in the +x direction.The electric field at a certain point is, E = 0.082 V/m

    We need to find the magnetic vector of the wave at the point P at that instant.

    The relation between electric field and magnetic field is given by :

    c=\dfrac{E}{B}

    c is speed of light

    B is magnetic field

    B=\dfrac{E}{c}\\\\B=\dfrac{0.082}{3\times 10^8}\\\\B=2.74\times 10^{-10}\ T

    So, the magnetic vector at point P at that instant is 2.74\times 10^{-10}\ T.
