Ultraviolet light is a type of electromagnetic radiation
UV light comes from the sun and is transmitted in waves or particles at different wavelengths an frequencies.
It makes black-light posters glow, and is responsible for summer tans. But too much exposure to UV radiation damage living tissue.
I love spicy foods and going to the gym.
