Infrared radiations are produced when a changing electric field creates a

a.) longitudinal wave perpendicular to it
b.) changing magnetic field parallel to it
c.) changing magnetic field perpendicular to it
d.) longitudinal wave parallel to it

Option (C)

Explanation:

The electromagnetic waves are produced by accelerating charge or the oscillating charge particles.

When electric field vector and magnetic field vector are at right angles to each other interacts, then electromagnetic waves are produced. They propagate in the perpendicular direction of both electric field vector and magnetic field vector.

The examples of electromagnetic waves are gamma rays, X rays, visible rays, infrared rays, micro waves, etc.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
