UV and IR radiation are both electromagnetic radiations. They differ in wavelength (the distance traveled by the wave in the time of one period, which is related to frequency). UV has a shorter wavelength than IR, and is thus more energetic (because shorter wavelength also means higher frequency, and the energy of a single photon is proportional to its frequency.) The energy in each photon in the UV frequency range is enough to wreak havoc with the structures of many moelcules, and thus cause a wide range of damage. This can be damage to tissue (as in a sunburn) or to DNA molecules (causing risk of skin cancer) or something relatively harmless, like the activation of a mechanism in the skin that increases pigmentation (i.e., a suntan.) This is also why the sun has a bleaching effect on the colors of many objects (the UV alters or destroys the molecules that provide the color) and causes others to become weak or brittle.
IR photons, on the other hand, have only enough energy to shake molecules around a little, which makes material hot but doesn't do any real damage (unless there's enough to make it reallyhot.) That's why IR is sometimes erroneously referred to as "heat rays."
Because the ultraviolet rays can burn your skin, cause skin cancer, damage your eyes, and harm/kill living cells.
Infrared photons have longer wavelengths than ultraviolet protons, which means that they have less energy with which to damage cells.
Ultraviolet radiation has more energy. E = hf
yes way more harmful
infrared cuz its more harmful
Infrared radiation has a lower frequency than optical light as it is below the red end of the spectrum. "Infra" means below, making "infrared" meaning "below red. On the other hand, ultraviolet radiation has a higher frequency than optical light as it is above the violet end of the spectrum. "Ultra" means "above or greater", making ultraviolet meaning "above violet". The answer to your question would be: ultraviolet radiation has more electromagnetic energy than infrared radiation.
ultraviolet has more energy.
When a molecule absorbs visible or ultraviolet radiation, electrons in their ground state are promoted to higher states. Through various types of decay, the electrons fall back to their ground states. During this process, some infrared radiation is emitted, which is felt as heat. Black materials emit more infrared radiation because most of the decay of electrons from excited states to ground states involves infrared radiation emission.
Infrared waves have far less energy than ultraviolet, being much further down the spectrum.
True , because the warmer objects give off more infrared radiation than cooler objects ..
Ultraviolet with its higher frequency and shorter wavelength carries more energy then infrared.
X-rays have the highest frequency in the electromagnetic spectrum.
Infrared radiation has a lower frequency than optical light as it is below the red end of the spectrum. "Infra" means below, making "infrared" meaning "below red. On the other hand, ultraviolet radiation has a higher frequency than optical light as it is above the violet end of the spectrum.

No, they are not. X-rays have a higher energy than UV radiation, and they have the potential to do more damage to tissue.
im 75% positive that it does penetrate deeper than infrared radiation.
No. Infrared (IR) light is longer wavelength (lower frequency) light and is of lower electromagnetic energy than shorter wavelength (higher frequency) ultraviolet (UV) light. Note that our skin "senses" infrared light (which we normally think of as heat) in a different way than it does ultraviolet light. This may account for the difference in the way it "feels" when we're exposed to light of the two energies. To be clear, ultraviolet light has higher energy photon for photon than infrared light. If both are absorbed by the skin, the reaction of the skin will be slightly different, but the energy imparted to the skin will be greater with the UV light that the IR light.
Ultraviolet rays have more energy and a higher frequency, while an Infrared ray is essentially heat, which has less radiation, and a longer wavelength. Also, they are located lower of the Electromagnetic Spectrum.
No, not in general. It is rather the other way around. Infrared radiation is electromagnetic radiation, and electromagnetic radiation spans multiple types of radiation, from microwaves, light, infrared, ultraviolet, radio, and more. So electromagnetic radiation could be infrared, but that is just one type of electromagnetic radiation
ultraviolet has more energy.
On the elecromagnetic spectrum, gamma rays have much more energy
Well there's many ways. One is from the sun's electromagnetic waves that have infrared radiation, white light (which is all colors of the rainbow), and ultraviolet radiation in case you wanted to know more about them.
No.
