Final answer:
White and Blue lights, specifically ultraviolet light, have both chemical and germicidal effects. Ultraviolet light can disrupt cell reproduction, kill bacteria, and trigger the production of vitamin D in the skin.
Step-by-step explanation:
White and Blue lights are considered to have both chemical and germicidal effects. UV light, which is a form of ultraviolet light, has the ability to disrupt cell reproduction and kill bacteria. UV light can cause the formation of thymine dimers within DNA, leading to mutations and microbial death. It is commonly used as a sterilizer in various settings, such as surgical suites, biological safety cabinets, and water purification systems. UV light is also beneficial as it triggers the production of vitamin D in the skin.
