Is infrared radiation part of the electromagnetic radiation?

Answer:
Yes it is. Infrared is the same physical phenomenon as radio, light, and microwaves.
The only difference among them is their wavelengths (frequencies).

Infrared is our name for electromagnetic radiation with wavelength just longer than red light ...
long enough so that our eyes don't respond to it.
