I'm arguing with a friend of mine on whether the light emitted from the sun is of the same type of that emitted by a bulb. Her insistent ignorance is laughable, unless I'm wrong...
She's talking about how light from the bulb is "artificial" ...
I've tried explaining that that makes no sense, and the only difference between the light is the way they're produced, and the intensities across their spectra.
The bulb will emit minuscule amounts of varying wave-lengths, but with the intensity focused around visible light, right?
The Sun will produce higher intensities of different types of wave-lengths, right?
Her counter-argument is that light bulbs don't inflict harm (via harmful radiation, like the sun).
