Infrared Radiation.
To produce thermogram it needs infrared wave. It is a radiant energy which cannot be seen by naked eyes and it was discovered by Sir William Herschel, an astronomer in the year 1800.
Light is an example of a electromagnetic wave.
A gamma ray is a type of electromagnetic wave that has the highest frequency and energy in the electromagnetic spectrum. It is a form of ionizing radiation.
Radio waves are a type of electromagnetic wave. They do not require a medium to travel through and can travel through a vacuum, unlike mechanical waves which require a medium, such as air or water, to propagate.

I would rather say that light IS a wave, not that it HAS a wave. It is a type of electromagnetic wave.
No, sound is not a type of electromagnetic wave. Sound is actually a mechanical wave that requires a medium (such as air, water, or solids) to travel through, while electromagnetic waves like light do not require a medium and can travel through a vacuum.
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
