A few days ago in my science class, we learned about waves of the electromagnetic spectrum. Then, my teacher assigned my class a project to research one of the electromagnetic waves, and the electromagnetic wave I chose was ultraviolet rays! The three interesting facts I learned about ultraviolet waves are: * Ultraviolet rays can cause skin cancer, premature aging, and problems with the immune system.* Ultraviolet rays can kill bacteria
* Sunlight is the major source of ultraviolet rays
In my opinion, I think that ultraviolet rays are helpful but dangerous and that everyone should do whatever it takes to protect their skin from ultraviolet rays in order to prevent the risk of skin cancer. So remember to always wear sunscreen when you are out in the sun.
