Different uses of infrared radiation


It is used for our remote controls and for our communications, for night vision glasses and for astronomy Yeah i think that is all I could give.. Hope it helps

Near-infrared rays are used in electronic applications like TV remote sensors and photography. Their applications can be somewhat similar to visible light applications since their wavelength ranges are close. Far infrared rays are more thermal in nature. Anything generating heat gives out far-infrared radiation.

Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV.


Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark.

Aside from sight, there are other important uses for visible light. We concentrate visible light to make lasers to use in everything from surgery, to CD players to laser pointers. Visible light waves also make our TV, computer and cell phone screens work

Ultraviolet rays can be used to kill microbes. Hospitals use UV lamps to sterilise surgical equipment and the air in operating theatres. Food and drug companies also use UV lamps to sterilise their products.





We use infrared radiation in many ways, including thermal imaging cameras, remote controls, fiber optic cables, infrared astronomy, and meteorology. The fact that water vapor and other greenhouses gases absorb infrared is part of why the greenhouse effect happens


4. A.She has a fever. Her temperature is 38.3 0C.

5..A.Heat is expressed in terms of Joules or calories.
