Final answer:
High frequency, such as ultraviolet (UV) light, can be useful in the treatment of microorganisms due to its germicidal effect. UV light causes mutations in DNA, leading to the death of microorganisms. It is commonly used in water purification systems, surgical suites, and biological safety cabinets.
Step-by-step explanation:
High frequency may be useful in the treatment of microorganisms due to its germicidal effect. One example of high-frequency radiation that is used for disinfection is ultraviolet (UV) light. UV light can cause thymine dimers to form in DNA, leading to mutations that can kill microorganisms. UV light is commonly used in water purification systems, surgical suites, and biological safety cabinets.
