UVB rays have the shortest wavelength of all the UV radiation.

They also increase the risk of developing melanoma, the deadliest form of skin cancer. UVA rays are responsible for causing wrinkles, age spots, and other signs of aging.
UVA rays are not very harmful to humans, although they do damage our skin. They are also the most commonly known type of UV radiation. UVA rays have the longest wavelength of all the UV rays. As we said earlier, UV radiation is made up of three separate wavelengths: UVA, UVB, and UVC. High-frequency waves are typically associated with high energy, while low-frequency waves tend to be associated with lower energy. Low-frequency waves are typically associated with lower frequencies, meaning that they travel slower. High-frequency waves are usually associated with higher frequencies, meaning that they move quickly. In terms of UV radiation, high-frequency waves are considered high energy waves, while low-frequency waves are considered low energy waves. Waves with shorter lengths are called high-frequency waves, while longer waves are low-frequency waves. There are many kinds of waves, including sound waves, radio waves, and light waves. What Is UV Wavelength?Ī UV wavelength is the length of the wave itself. UVC rays are useful for disinfecting surfaces, but they aren't strong enough to penetrate deep into our skin. UVB rays help prevent sunburns, which can lead to skin cancer later in life. UVA rays help keep our skin healthy and youthful-looking. However, there are some benefits associated with each kind of radiation. They are also used in air purifiers and water filters because they kill bacteria and viruses.Īll three types of UV radiation are beneficial in their own ways. UVC rays are used in some types of germicidal lamps, such as those used in hospitals. These rays are too short to penetrate human skin, so you shouldn't worry about getting exposed to them. Mercury vapor bulbs are extremely efficient at emitting UVC rays, and they are much stronger than natural sunlight. Tanning beds emit UVC rays, however, because they contain mercury vapor bulbs. Most people who use tanning beds receive no exposure to UVC rays. UVC rays are the least common form of UV radiation, and they are rarely found naturally. These rays can also cause DNA mutations, which may result in birth defects. UVB rays can cause skin cancer, cataract, and even blindness. Because of their power, they are often used in tanning beds.īecause they are so strong, they are also dangerous. They tend to be more powerful than UVA rays, but they only penetrate about 1/10th of an inch into the skin. UVB rays are the second most common kind of UV radiation. In addition, UVA rays can affect the immune system by decreasing the production of white blood cells.

They also cause the formation of free radicals in the body, which can lead to premature aging. UVA rays are responsible for damaging collagen fibers, making wrinkles appear sooner. They are what causes sunburn, and they also contribute to aging of the skin.
UVA rays are the most common form of UV radiation. Different Types Of UV RaysĪs we mentioned before, there are different wavelengths of UV light. These rays are used in tanning beds because they help make the skin brown faster. UVC rays do not penetrate glass at all, so you won't get any exposure to these rays unless you're using a tanning bed. However, UVA rays don't penetrate glass very well, so you'll need to cover up if you're outside for long periods. For example, UVA rays penetrate deeper into the skin than UVB rays, so they can burn through your skin to reach the blood vessels underneath. They also affect plants, causing them to grow more slowly and produce less food than normal.ĭifferent wavelengths of UV have different effects. The wavelengths in this range are harmful to humans because they cause sunburn, skin cancer, cataracts, and other eye damage. This means that it can be divided into three parts: ultraviolet A (UVA), which ranges from 320 nm to 380 nm ultraviolet B (UVB) which ranges from 280 nm to 320 nm and ultraviolet C (UVC), which ranges from 100 nm to 280 nm. It has a wavelength range from about 10 nm to 400 nm (0.1 μm to 40 μm). UV is the part of the electromagnetic spectrum that lies between visible light and x-rays, and it’s also known as ultraviolet radiation or UVR.
