No, not in general. It is rather the other way around. Infrared radiation is electromagnetic radiation, and electromagnetic radiation spans multiple types of radiation, from microwaves, light,...
Visible radiation (a.k.a. light) is the wavelengths we can see. Infrared radiation lies down below the red end of the spectrum that we can see, hence infra red. But we can make device that both...
No, if you look at a chart of the electromagnetic spectrum, you will see that microwave radiation is a longer wavelength ( approx. 1x10^8 Hz to 1x10^11Hz). Infrared is a smaller wavelength - approx...
