This is from episode 11 of Iron Man: Armored Adventures
basically Iron Man gets hit with a big laser and i'm wondering if there's any way to calculate it's energy besides just the destruction it caused

If it caused an explosion, you can calculate those based on size without destruction. If it just caused a flash of light, then no. Luminosity calcs aren’t very useful on this small a scale.

there was no explosion but it left behind a crater, i was just wondering if there was a way to calc it outside of measuring the crater
i ended up using deflagration to measure the strength of the laser
