is uv the same as infrared?

While IR represents electromagnetic radiation with wavelengths longer than those of visible light, UV represents wavelengths shorter than visible light. The IR extends from the red edge of the visible spectrum (700 nm) to as high as 1 mm.

It is common for individuals to wrongly assume that infrared and radiant heaters are two different types. However, infrared and radiant heat is fairly similar and these types of heaters are one in the same. Infrared or radiant heating is a type of heat energy that is transferred from an infrared radiant energy source.

Red light is visible and is most effective for use on the surface of the skin. Red light occupies the “long end” of the visible spectrum with wavelengths of 630nm-700nm. Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body.

Infrared radiation is a part of the electromagnetic spectrum. This is a spectrum of waves that also includes light. Infrared is also called thermal radiation and is one way in which heat is transferred. Infrared is emitted (given off), absorbed (taken in) and reflected by all objects.

Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. ... The common designations are radio waves,microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma-rays.

Ultraviolet (UV) radiation is defined as that portion of the electromagnetic spectrum between x rays and visible light, i.e., between 40 and 400 nm (30–3 eV). ... UVC is almost never observed in nature because it is absorbed completely in the atmosphere, as are Far UV and Vacuum UV.

Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays. ... Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact.

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, that is, in the range 10 nm to 400 nm, corresponding to photon energies from 3 eV to 124 eV (1 eV = 1.6e-19 J; EM radiation with frequencies higher than those of visible light are often ...

"Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.

IR is a type of electromagnetic radiation, a continuum of frequencies produced when atoms absorb and then release energy. ... Similar to the visible light spectrum, which ranges from violet (the shortest visible-light wavelength) to red (longest wavelength), infrared radiation has its own range of wavelengths.

Camera Vision Infrared Radiation (IR) is a wavelength longer than visible light but shorter than radio waves (750nm to 1nm).

Night vision detects visible light while infrared detects radiated heat. Night vision needs a little amount of light while infrared doesn't. Infrared is better for camouflaged targets than night vision. Night vision can be counteracted by bright light while infracted can counteracted by cooling.

Visible light sits in the region with ultraviolet (UV) to the left of the spectrum and infrared (IR) to the right. It is a form of electromagnetic radiation which can be subdivided into seven colors. It's probably the most familiar to you because it is the only region on the spectrum that is visible to most human eyes.

Visible light is only part of a rainbow. Infrared radiation exists just beyond visible red light, while ultraviolet is just beyond violet. There are also radio waves (beyond infrared), x-rays (beyond ultraviolet), and gamma radiation (beyond x-rays).
1109507
The higher energy, shorter wavelength far UV region spans wavelengths between 91 and 200 nm. Extreme UV radiation has the shortest wavelength range and highest energies of the regions of the ultraviolet spectrum, and lies on the border between UV and X-ray radiation.
1189451
Shortwave radiation (visible light) contains a lot of energy; longwave radiation (infrared light) contains less energy than shortwave radiation (shortwave radiation has a shorter wavelength than longwave radation). ... The ground heats up and re-emits energy as longwave radiation in the form of infrared rays.

Infrared (IR) refers to a part of the EM spectrum below the visible light region but above Tera hertz. Laser diodes refer to a semiconductor device that emits coherent radiation. Lasers emit the wavelength of light that they are designed for, some are visible, some are IR, some are ultra violet.
