In the military, night vision goggles are used to pull off secret missions into areas that are very dangerous. for this reason, the soldiers try to infiltrate at night so they can't be seen. thermal-imaging devices are often used as well to locate people on these highly secretive missions. what type of electromagnetic radiation is being utilized? a) radio waves b) gamma rays c) ultraviolet rays d) infrared waves

The correct option is D-Infrared waves

Infrared waves are being used in thermal imaging devices. Thermal imaging is basically a method that is used to enhance and improve objects visibility in dark environments.

Thermal imaging does works in environments without any ambient lights and can penetrate obscurants like fog and haze.
