Study Notes

Ultraviolet (UV) light is a type of electromagnetic radiation with shorter wavelengths than visible light.
UV light has a higher frequency than visible light and is categorized as electromagnetic radiation with wavelengths between 10 and 400 nanometers (nm).
Electromagnetic radiation consists of waves of electric and magnetic fields that propagate through space.
UV light is a form of electromagnetic radiation that can travel through space without a medium.

UV light has shorter wavelengths than visible light, meaning it has higher energy.
The wavelength of UV light ranges from 10 to 400 nm.
UV light can be divided into smaller sections with different effects, including long-wavelength UV (UV-A) and short-wavelength UV (UV-B and UV-C).

Long-wavelength UV (UV-A) can be beneficial, while short-wavelength UV (UV-B and UV-C) can be harmful.
UV light can cause DNA damage and lead to the development of skin cancers.
UV light can also cause damage to the eyes, including retinal burns and cataracts.

UV-A (320-400 nm) has the longest wavelength and lowest energy.
UV-B (290-320 nm) has shorter wavelengths than UV-A and has both beneficial and harmful effects.
UV-C (220-290 nm), far UV (190-220 nm), and vacuum UV (40-190 nm) all have sufficient energy to cause more significant damage to DNA.

UV light has both beneficial and harmful effects, and is used in various applications, including medicine and industry.
UV light is used in fluorescent dyes, crime scene investigating, water and food sterilization, and research science.
However, excess sun exposure can cause sunburn, damage collagen and vitamin A in the skin, and lead to the development of skin cancers.

The Sun is the largest source of UV light, emitting UV light at all wavelengths.
Artificial sources of UV light include tanning beds, arc lights, diodes, and lasers.
Black lights, UV light-emitting diodes (LEDs), and germicide lamps are also common sources of UV light.
