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
You have to look at two things:
What wavelength is the detector measuring and how much of that is absorbed by the atmosphere? Large portions of the UV spectrum are absorbed by the atmosphere, and I’m not sure, but it’s possible the Sun only emits certain wavelengths of UV.
The total output of the Sun would be trillions of times what your flashlight produces, but you may not see much of it (which is a good thing).
