ULTRAVIOLET LIGHT RAYS

By: Natalie Alexander and Elisa Desclous

Firstly… What is ultraviolet?

Ultraviolet means “beyond violet.” Ultraviolet light rays

(UV Rays) follow visible light on the spectrum, the last color of which is violet, so this name makes sense!

Characteristics

UV Rays have slightly shorter wavelengths and slightly higher

frequencies than visible light, putting it higher on the scale than it.

UV Rays and Your Health

UV Rays are actually sun rays. These rays can make you healthier (they

make your cells produce vitamin D) but they can also have negative effects on

your health. These rays can cause short-term damage such as sunburn,

or long term damage like skin cancer. Prevent these with sunscreen!

Everyday Life

UV Rays can have more uses than just lighting your room. They can also

create electricity through solar panels that can be used for powering homes,

businesses, and cars!
