Sunburn produces cell damge in the skin. Why is ultraviolet radiation capable of producing this damage while visible radiation even if more intense is not?
By the wording of your question, I'm assuming you know some basic physics, but for those who don't, I'll do a quick summary.
Electromagnetic radiation, of which both visible light and UV radiation are a part, consists of photons (light particle-waves) of varying wavelengths. The wavelength of the radiation determines the energy it carries, they are inversely proportional. Thus, shorter wavelengths have a higher energy, and longer wavelengths have a lower energy.
The DNA inside skin cells can essentially be viewed as long, helical chain of molecules that are bonded together in specific ways. These bonds have specific energies associated with them, and if radiation with the right amount of energy (and hence the right wavelength) hits it, this bond can be broken. Usually, the cell is able to repair this damage. This is a complicated process which can easily be looked up, but I won't go into it here. Sometimes, however, mistakes occur during this repair, and these mistakes are replicated when the DNA is reproduced for further skin cell production.
Now that the background is established, back to the question. UV radiation, having a shorter wavelength than that of visible light, is energetic enough to break bonds in DNA, and thus to damage skin cells.

A sunburn is caused by overexposure to what kind of ray?
One type of radiation that CAN give you sunburn is UV radiation
Which type of energy cause sunburn?
Do you mean 'Which electromagnetic wave in the electromagnetic spectrum causes sunburn? The answer is Ultraviolet (UV), which is what is used in sunbeds and therefore damages and colours your skin cells.
Is getting a sunburn radiation or convection?
Getting a sunburn is an example of radiation. Ultraviolet (UV) radiation from the sun penetrates the skin and damages cells, leading to the inflammation and redness associated with sunburn. Convection, on the other hand, involves the transfer of heat through air or a fluid.
Can an x-ray cause sunburn to a skier on a white snow packed mountain?
No, an x-ray cannot cause sunburn on a skier. X-rays are a form of electromagnetic radiation that can penetrate the body to create an image, but they do not emit the type of ultraviolet radiation that causes sunburn. Sunburn occurs due to exposure to ultraviolet rays from the sun, which x-rays do not produce.
What part of the electromagnetic spectrum can cause sunburn?
Ultraviolet (UV) radiation, specifically UVA and UVB rays, from the sun can cause sunburn on the skin. UVB rays are typically responsible for sunburn, while UVA rays can contribute to skin damage and aging. It is important to protect the skin from UV radiation by using sunscreen and seeking shade when necessary.
What solar radiation is the most powerful?
Ultraviolet (UV) radiation is the most powerful form of solar radiation because it has the highest energy levels. It can have both beneficial and harmful effects on living organisms, including the ability to cause sunburn and skin damage.
What are two examples of ultraviolet waves?
Two examples of ultraviolet waves are UVA (long-wave ultraviolet) and UVB (short-wave ultraviolet). UVA radiation can penetrate deeper into the skin and is associated with skin aging, while UVB radiation is responsible for sunburn and can contribute to skin cancer.
What wave causes sunburn?
Ultraviolet (UV) radiation from the sun is the primary cause of sunburn. Specifically, UVB rays are mostly responsible for causing sunburn by damaging the outer layers of the skin. It is important to protect the skin from UV exposure to prevent sunburn and reduce the risk of skin damage and skin cancer.
What are the effects of the ultraviolet radiation?
over exposure can lead to sunburn, inflammation, and tanning. Over time it may lead to blindness or cancer.
Does infrared radiation cause burns?
Yes, prolonged exposure to infrared radiation can cause burns. Infrared radiation can penetrate the skin and heat tissues beneath the skin surface, resulting in burns similar to those caused by exposure to heat sources like fire or hot objects.
Can ultraviolet light be felt as heat?
No, ultraviolet light cannot be felt as heat. Ultraviolet light is a form of electromagnetic radiation that is not perceived by touch. It can, however, cause skin damage and sunburn if exposed to the skin for a prolonged period.
The following types of energies that the Earth receives from the Sun which type of energy causes sunburn?
Ultraviolet (UV) radiation is the type of energy from the Sun that causes sunburn on Earth. UV radiation, specifically UVB rays, can penetrate the skin and damage cells, leading to inflammation and redness commonly associated with sunburn.
