Difference Between Infrared and Ultraviolet Radiation

IR and UV radiation are a small part of the electromagnetic spectrum. The visible light has a wavelength of 380 nm to 760 nm. The area alongside with a longer wavelength is the IR spectrum. ... The area next to the visible light, with a shorter wavelength, is the UV spectrum.

What is the difference between infrared and ultraviolet rays?

The EM radiation most immediately lower-frequency than visible light is called infrared, and the EM radiation most immediately higher-frequency is called ultraviolet. ...

Which is more harmful ultraviolet or infrared?

In terms of wavelength, ultraviolet radiation has shorter wavelengths than visible radiation, which have shorter wavelengths than infrared. ... Of more importance to us, ultraviolet photons have enough energy to damage or destroy DNA, visible and infrared photons do not.

What is the difference between radiation and infrared radiation?

Infrared light is part of the electromagnetic spectrum, and is an electromagnetic form of radiation. It comes from heat or thermal radiation, and it is not visible to the naked eye. More radiation is produced as temperature increases.

What damage can Infrared cause?

IR, particularly IR-A or near IR [700nm-1400nm], raises the internal temperature of the eye, essentially “baking” it. Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively.

What is the uses of infrared?

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.

Can infrared light give you cancer?

Skin cancer is not expected from exposure to IR. However, increased skin temperature can reduce DNA repair efficiency, and promote skin cancer that is initiated by other agents. Skin thickness may also increase due to repeated IR exposures.

What are the negative effects of infrared radiation?

IR raises the internal temperature of the eye, virtually “baking” it. Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. Don't stare at the sun! The infrared radiation in the sunlight damages skin.

Is infrared bad for your eyes?

Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.
