Infrared radiations are produced when a changing electric field creates a

longitudinal wave parallel to it
longitudinal wave perpendicular to it
changing magnetic field parallel to it
changing magnetic field perpendicular to it

Option (d)

Explanation:

When an oscillating electric and magnetic fields interacts each other perpendicularly then electromagnetic radiations are produced.

Here the changing magnetic field is created perpendicular to electric field
