Which type of radiation is categorized by wavelength in three bands, namely UV-A, UV-B, and UV-C?

• A. X-rays
• B. Infrared (IR)
• C. Ultraviolet (UV)
• D. Microwaves

Answer: (C)

Ultraviolet (UV) radiation is categorized by its wavelength into three distinct bands: UV-A, UV-B, and UV-C. This classification is essential in various fields, including health, environmental science, and materials research, as each band has different properties and effects on biological organisms and materials. UV-A rays have the longest wavelength and are associated with skin aging and some types of skin cancer. UV-B rays have a medium wavelength and are mainly responsible for causing sunburns and contributing to skin cancer. UV-C rays, which have the shortest wavelength, are primarily germicidal and are used in sterilization processes. Understanding these bands helps in assessing risks and applying protective measures against harmful effects of UV radiation. This comprehensive categorization allows scientists and health professionals to effectively communicate risks and develop guidelines for UV exposure.
