I thought sunlight was ionizing radiation? We literally get irradiation damage (sunburns) from it.

- marginalia_nu 4y agoSure. The energetic end of the visible spectrum is weakly ionizing, more so in the UV spectrum. But ionization is not why the bug starts smoking. You can start a fire with a sufficiently high powered infrared laser too.
- nickff 4y agoI think it's worth noting that a magnifying glass actually blocks/filters out UVB, and substantially reduces UVA. Feynman famously watched Trinity with only a truck windshield to protect him. https://en.wikipedia.org/wiki/Trinity_(nuclear_test) https://en.wikipedia.org/wiki/Trinity_(nuclear_test)
