Sunlight is composed of three types of ultraviolet (UV) light: UVA, UVB, and UVC. UVA accounts for about 95% of the UV light that reaches the Earth's surface, while UVB makes up the remaining 5%. UVC is absorbed by the Earth's atmosphere and does not reach the surface.
UV light is a component of sunlight, but sunlight also contains other types of light. UV light is a type of electromagnetic radiation that is not visible to the human eye.
UV light and sunlight both contain ultraviolet radiation, but sunlight is a broader spectrum of light that includes visible and infrared radiation. UV light, specifically UVA and UVB rays, can penetrate the skin and cause damage such as sunburn, premature aging, and an increased risk of skin cancer. Sunlight, on the other hand, can have both positive and negative effects on the skin, such as providing vitamin D but also increasing the risk of UV-related skin damage.
A UV activated shirt changes color in response to sunlight exposure because the special dye in the fabric reacts to ultraviolet (UV) light. When the shirt is exposed to sunlight, the UV rays cause the dye molecules to change structure, which results in a color change. This process is reversible, meaning the shirt will return to its original color when no longer exposed to UV light.
Fabrics that fluoresce under ultraviolet light absorb the UV energy and re-emit it as visible light, which gives them a bright appearance in sunlight. This is because the sunlight contains UV light that can excite the fluorescence in the fabric, causing it to emit light in the visible spectrum.
Ultraviolet (UV) light is formed by the sun as a part of the electromagnetic spectrum. It is produced by the sun's energy and accounts for a small portion of the sunlight that reaches the Earth. UV light is also emitted by certain artificial sources like UV lamps and black lights.
UV light is a component of sunlight, but sunlight also contains other types of light. UV light is a type of electromagnetic radiation that is not visible to the human eye.
Most of the light in sunlight is ultraviolet light, also known as UV light/rays.
Stay out of sunlight and other UV light sources as much as possible. While not as drastic as dying your hair. Long duration exposure to UV light does brighten your hair.
The most common source for UV light would be the sun. Generally everyone is exposed to UV light when they go outside during the day or sit in the sunlight in their home.
Ultraviolet light is also known as UV light. Ultraviolet light is electromagnetic radiation wavelengths and is emitted in black lights, tanning lamps and sunlight.

Some examples of radiation and UV light include sunlight and ultraviolet light bulbs. Each produce special wavelengths of light which are not seen by the naked eye.
Ultraviolet (UV) light from the sun is absorbed by ozone in the Earth's atmosphere. Specifically, ozone absorbs UV-B and UV-C wavelengths of light, providing a protective layer that shields the planet's surface from harmful radiation.

they are not scared of artificial light for example light bulbs but they are scared of sunlight due to the UV rays
