    Question

    The angle between the direction of electric and magnetic fields of an electromagnetic wave is:

    A.

    90°

    B.

    45°

    C.

    D.

    180°

    Correct option is A

    The correct answer is: (a) 90°
    Explanation:
    · In an electromagnetic wave, the electric field (E) and magnetic field (B) are perpendicular to each other, and both are also perpendicular to the direction of wave propagation.
    · Hence, the angle between the electric and magnetic fields is 90 degrees.
    Information Booster:
    · EM waves are transverse in nature.
    · They do not require a medium for propagation.
    · The speed of EM waves in vacuum is 3 × 10⁸ m/s.
    · EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
    · James Clerk Maxwell formulated the theory of electromagnetism.
    · EM waves carry both energy and momentum.
