electromagnetic wave, and infrared radiation is part of the electromagnetic spectrum (shown below).&nbsp; An infrared camera shows us wavelengths of light beyond what our eyes can see, displayed on a false-color scale.&nbsp; Thermal radiation is emitted in the infrared range, so an IR camera is showing us heat radiated from different objects.&nbsp; Because of it&#8217;s longer wavelength, infrared radiation can transmit through some materials that visible light cannot, and this has applications to night vision, building inspection, astronomy, medical imaging, and climate
