explain why infrafred radiation are used for signals during war

Open in App

Solution

The wavelength of infrared radiation is above than that of visible light. So, this radiation can penetrate through the haze without being scattered. Due to this characteristic, it can be used as signals on distant objects obscured by atmospheric haze. Also, during war, it enables sharpshooters to see their targets in total darkness.
