Which of the following light waves from the sun cause sunburn? Waves we can see in the form of visible light Helps synthesize vitamin D, can cause sunburn Waves that give off heat
How do we protect ourselves from ultraviolet (UV) light?
How do we protect ourselves from ultraviolet light?
Lets test your sunscreen and see if it really does provide UV protection. To test our sunscreen types, we need to create a testing material that will change when we expose it to UV light. In this activity, we ll create a material that is phosphorescent.
