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

is it d pls help me

yes, d.

Yes, you are correct. Infrared radiation is produced when a changing magnetic field is perpendicular to a changing electric field.

Yes, you are correct! Infrared radiations are produced when a changing electric field creates a changing magnetic field perpendicular to it. This occurs in a process called electromagnetic induction.

To arrive at this answer, we can refer to Maxwell's equations, which describe the behavior of electric and magnetic fields. According to Maxwell's equations, a changing electric field produces a changing magnetic field, and vice versa. This relationship holds true for all electromagnetic waves, including infrared radiations.

Specifically, in the case of infrared radiations, an oscillating or changing electric field generates a perpendicular oscillating or changing magnetic field, and these two fields support each other as they propagate through space. This perpendicular relationship between the electric and magnetic fields characterizes the nature of electromagnetic waves, including infrared radiation.
