Question

write any 4 uses of infared waves​

Answer 1

Answer:

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.

Answer 2

1. Infrared is used in night vision equipment when there is insufficient visible light.
2. Infrared radiation can be used to remotely determine the temperature of objects (if the emissivity is known). This is termed thermography, or in the case of very hot objects in the NIR or visible it is termed pyrometry
3. 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.
4. Infrared light is even used to heat food sometimes - special lamps that emit thermal infrared waves are often used in fast food restaurants! Shorter, near infrared waves are not hot at all - in fact you cannot even feel them. These shorter wavelengths are the ones used by your TV's remote control.
