Cách sử dụng
Ultraviolet is a type of light that we can't see with our eyes because it's too strong. It's often used to describe the rays of the sun that can give you a sunburn or damage your skin if you're outside for too long without protection. In science, it's also used to describe a type of radiation that can be used to kill germs or treat diseases. So, when you hear the word 'ultraviolet,' it's usually referring to something that's really powerful and can be harmful if you're not careful.
