1、 Long wave UVA, with a wavelength ranging from 320nm to 400nm, is also known as long wave black spot effect ultraviolet. It has strong penetration, can penetrate glass and even 9 feet of water; And it exists all year round, whether cloudy or sunny, day or night. Degree of harm t...
UVB rays have slightly more energy than UVA rays. They have a short wavelength that can only reach the outer layer of your skin called the epidermis. UVB rays have been linked to skin burning. They also have an important role in the formation of skin cancers, especially a dangerous for...
UVA rays are more dangerous because they make up 95% of the light that reaches our skin and they have a long wavelength which means they can penetrate deeper into the skin. Since there doesn’t have to be sunshine – only light – for UVA rays to be present, UVA has an effect on ou...
Sunscreens are products that help prevent the sun’s harmful rays from reaching the skin’s surface. The sun emits harmful rays that reach the earth’s surface. These ultraviolet rays are divided into two types: ultraviolet A (UVA) and ultraviolet B (UVB
electromagnetic radiation, along with radio waves, microwaves, and radioactive waves found in places likeChernobyl. By the time sunlight reaches you on Earth after traveling through space, its radiation comes in two flavors depending on the wavelength: Ultraviolet A (UVA) and Ultraviolet B (UVB)....
Such an approach would enable, perhaps, an action spectrum to be constructed for the immune response based on UV wavelength or waveband, in addition to a comparison of the IPF of one sunscreen with another. Two such systems have been described recently, details of which are the subject of ...
Ad Sunburn is inflamed, painful skin that feels hot to the touch. It's caused by too much exposure to UVlight. That UV light may be from the sun or artificial sources, such as sunlamps and tanning beds. UVA is the wavelength of light that can penetrate to the deep layers of skin an...

Some microbes (such as bacteria) are destroyed by UV light depending on the wavelength; ultraviolet A (UVA) generally destroys non-nuclear cellular components, whereas ultraviolet B (UVB) and ultraviolet C (UVC) generally destroy nuclei (Parsa et al., 2021). Furthermore, UVC is effective ...
