UV light (particularly UV-B and UV-C, which are regions of the spectrum with shorter wavelengths than the UV-A part) can cause skin cancer. It does this because the DNA molecules in your body absorb UV light, and the light has enough energy to break bonds in the DNA, causing harmful rearrangements in your genetic code. When cells with damaged DNA reproduce, that can result in cancerous cells. See more details here: http://en.wikipedia.org/wiki/Ultraviolet

How does the scattering of tiny particels in the air affect the colors of the sky at sunrise and sunset?
The tiny particles in the air affect the colors of the sky at sunrise and sunset because they cause the suns rays to change directions. When this occurs it changes the suns rays and causes different color arrays.

What does the abbreviation UVB stand for?
UVB is a commonly used acronym that stands for ultraviolet B rays. UVB rays are short waves and are believed to be the rays which are responsible for sunburn.
What uv light is Melanin activating ray?
Melanin activates in response to UVA and UVB rays from the sun. UVA rays penetrate deeper into the skin and are associated with tanning, while UVB rays primarily affect the outer layers of the skin and are responsible for causing sunburn.
Are UVA rays more prevalent than UVB rays in sunlight?
Yes, UVA rays are more prevalent than UVB rays in sunlight. UVB rays are more intense but make up a smaller portion of the UV radiation that reaches the Earth's surface.
Are UVA rays more prevalent than UVB rays in sunlight, and how do they differ in terms of their impact on the skin?
Yes, UVA rays are more prevalent than UVB rays in sunlight. UVA rays penetrate deeper into the skin and can cause long-term damage, such as premature aging and skin cancer. UVB rays primarily affect the outer layers of the skin and are responsible for sunburns and skin cancer. It is important to protect your skin from both types of UV rays to prevent damage.
How many altraviolet rays are there?
There are three types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA rays have the longest wavelength, UVB rays have a medium wavelength, and UVC rays have the shortest wavelength. UVC rays are mostly absorbed by the Earth's atmosphere and do not reach the surface.
Does ultraviolet rays cause sunburns?
There are 2 types of ultra violet rays, UVA and UVB. UVA causes aging and wrinkles, and UVB causes the sun burns.
Which light rays can cause skin damage similar to sunburn?
There are three types of rays- UVA, UVB and UVC. UVB and UVA act differently upon our skin and do not equally damage it. The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays. The UVA rays are longer so reach the inner state of the skin and causes skin damage.
What percentage of UV rays does the Sun produce?
The Sun produces three types of UV rays: UVA, UVB, and UVC. Roughly 95% of the UV rays that reach the Earth's surface are UVA rays, while about 5% are UVB rays. UVC rays are mostly absorbed by the Earth's atmosphere.
How does melanoma occur?
UVA rays penetrate the skin more deeply and can cause melanoma in susceptible people. UVB rays, which don't penetrate as deeply, cause sunburn and wrinkling.
What wavelengths of light causes surface skin burning?
Ultraviolet (UV) radiation, specifically UVA and UVB rays, are the wavelengths of light that can cause skin burning. UVB rays are primarily responsible for sunburn, while UVA rays penetrate deeper into the skin and contribute to skin aging and wrinkling. It is important to protect your skin from both UVA and UVB rays by using sunscreen.
Can uva and uvb rays pass through normal glass?
Yes, while UVA rays can pass through normal glass, UVB rays can be partially blocked by glass. This is why it's still important to apply sunscreen when indoors or in a car to protect against UVA rays.
How many ultraviolet rays are there?
There are three main types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA and UVB are the ones that reach the Earth's surface, while UVC is mostly absorbed by the Earth's atmosphere.
