The lower frequency boundary is open to discussion; it is difficult to know where the far infrared becomes the "millimetric" microwaves. Somewhere round about 10THz (=1013Hz) The upper bound is easy - if it is just too low a frequency to see, then it is infrared. 384THz (=3.84 X 1014Hz)

What is the name of technology that uses infared light waves?

Is infared a transverse or longitudinal wave?
No doubt about it; infra red rays are transverse in nature. Only sound waves are longitudinal. Electromagnetic waves are transverse waves. Infra red belongs to that family of electromagnetic waves.
