Its 0.7 to 300 Micrometers.
electromagn etic wave
Heat transfer by radiation occurs in the infra-red part of the electromagnetic wave spectrum, because matter emits and absorbs radiation with that range of frequencies.
Infra red waves
No. If anything, that'd be infra red.
Heat is transported through Infra red. It is an electromagnetic wave
Heat radiation is mainly associated with infrared radiation.
Visible and infra red parts of the EM spectrum
Usually infra red, but I have seen some that use ultrasound.
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.
Increased pressure in a longitudinal wave corresponds to the region of compression, where particles are pushed closer together. This region represents the peak of the wave.
-- infra red -- heat -- microwave -- radio -- utility power
Is the balance between incoming short wave solar radiation (infra) and outgoing long wave solar radiation (TERESTRIAL) to avoid over cooling and overheating of the atmosphere.
