Some insects, like bees, can see light of shorter wavelengths than humans can see. What kind of radiation do you think a bee sees?
Sunburn produces cell damage in the skin. Why is ultraviolet radiation capable of producing this damage, while visible radiation, even if more intense, is not?
Why do you suppose ultraviolet rays from the sun are more damaging to the skin than visible light?

- Speculate as to why UV light causes sunburn, whereas visible light does not.arrow_forwardFor years, exposure to ultra-violet radiation from prolonged time in the sun has been the major identified cause of skin cancer. New research is showing that ultra-violet is not the only type of radiation from the sun that can increase the risk of skin cancer. Rates of skin cancer among pilots are twice that of non-pilots, but the glass used in planes blocks most the ultra-violet radiation. Pilots are also exposed to x-rays from the sun during flight. The x-rays that pilots are exposed to in one day of work are equivalent to a chest x-ray. Although getting an x-ray for medical reasons is believed to be safe, researchers believe that the frequent exposer that pilots experience increases their risk for skin cancer.
