When I measured the sun, it gave a UV index of 6. When I measured the uv flashlight, it gave a uv index of 196. Is the sun not more powerful in UV than the flashlight?
In: Physics
Radiation is kind of like sound. The farther away you are, the less powerful it gets. Someone whispering in your ear is louder to you than an earthquake on the other side of the world. The sun puts off more UV radiation than the flashlight, but it’s much farther away, AND some of that radiation that DOES make it here gets blocked by the atmosphere.
