Can infrared radiation be reflected

WebThis reflection allows infrared radiation to transfer heat between the surface, water and the air. In a body of water, infrared light can only reach a certain distance below the surface. 90% of infrared radiation is … WebYou can show that the detector is responding to infra-red radiation by placing a simple aluminium reflector, painted black, between the radiation source (human body) and detector. The detector will show no effect. Infra-red photons are absorbed by the black coating; any microwaves noise will be reflected without any loss.

Infrared lights can reveal both the wave and particle nature at the same time. Infrared radiation can either be absorbed or reflected back depending on the surface nature of the material. It helps in increasing the thermal energy in the particles. Web14 hours ago · Because infrared stealth requires low absorption and high reflection, radar stealth requires high absorption and low emission. The key to solving this contradiction is to stratify control according to the wavelength difference of radar wave and infrared wave.
