UVB rays have the wave length ranges 315-280 nm. It is used in treatment for many skin disorders like vitiligo, eczema etc.
From the Related link (UVB Radiation...) below: "The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays and only reach the surface of the skin that is made up of the epidermis layer. The UVB radiation is absorbed by the stratum corneum on the epidermis surface. This stratum corneum is the dead cells layer - the visible layer of the skin. The UVA radiation is partly absorbed and blocked by the ozone layer before reaching Earth.
The UVA damage is deeper, as the UVA rays are longer than the UVB ones and reach the inner strata of the skin. They are responsible for causing the skin to lose its elasticity and wrinkling, leading to premature aging of the skin. They also can burn the skin, but at a deeper level. The UVA rays are not at all absorbed by the atmosphere and completely reach Earth.
Both UVA and UVB lead to skin cancer, whether it is malignant or benign. In the malignant type of cancer there is a tumor that appears as a consequence of abnormal proliferating skin cells. The uncontrollable growing of these cells leads to melanoma tumor forming, which in most of the cases is lethal."

Ultraviolet sun rays responsible for burning skin?
Ultraviolet (UV) sun rays, specifically UVB rays, are responsible for burning the skin and causing sunburn. When the skin is exposed to excessive UVB rays, it can lead to inflammation, redness, and blistering. It is important to protect the skin from these rays by using sunscreen and seeking shade during peak sun hours.
Describe how UV radiation penetrates the atmosphere and causes damage?
UV radiation from the sun penetrates the Earth's atmosphere and is divided into UVA, UVB, and UVC rays. UVC rays are absorbed by the ozone layer, while UVA and UVB rays reach the Earth's surface. UVB rays cause sunburn and skin cancer, while UVA rays penetrate deeper into the skin, causing premature aging and contributing to skin cancer risk. Long-term exposure to UV radiation can damage DNA, leading to mutations and skin cancer.
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 is the most harmful type of UV rays?
UVC rays are the most harmful type of UV rays, but they are mostly absorbed by the Earth's atmosphere and typically do not reach the surface. UVB rays are the next most harmful, as they can cause sunburn and increase the risk of skin cancer. UVB rays can also damage the DNA in skin cells.
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.
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 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.
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.
Ultraviolet sun rays responsible for burning skin?
Ultraviolet (UV) sun rays, specifically UVB rays, are responsible for burning the skin and causing sunburn. When the skin is exposed to excessive UVB rays, it can lead to inflammation, redness, and blistering. It is important to protect the skin from these rays by using sunscreen and seeking shade during peak sun hours.
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.
Describe how UV radiation penetrates the atmosphere and causes damage?
UV radiation from the sun penetrates the Earth's atmosphere and is divided into UVA, UVB, and UVC rays. UVC rays are absorbed by the ozone layer, while UVA and UVB rays reach the Earth's surface. UVB rays cause sunburn and skin cancer, while UVA rays penetrate deeper into the skin, causing premature aging and contributing to skin cancer risk. Long-term exposure to UV radiation can damage DNA, leading to mutations and skin cancer.
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 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 are three types of uv light?
UVA, UVB, and UVC are three types of ultraviolet (UV) light. UVA rays penetrate deep into the skin, contributing to skin aging. UVB rays are responsible for sunburns and increasing the risk of skin cancer. UVC rays are mostly absorbed by the Earth's ozone layer and do not reach the Earth's surface in significant amounts.
Is uv radiation harmful?
UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.
How many types of ultraviolet rays are there?
There are three main types of ultraviolet rays: UVA, UVB, and UVC. UVA rays penetrate deep into the skin and are the most commonly encountered in sunlight, UVB rays cause sunburn and are partially absorbed by the ozone layer, and UVC rays are absorbed by the Earth's atmosphere and do not typically reach the surface.
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.
