I recently did an experiment with the Crookes's Radiometer.
The radiometer was first placed under a 100W 1600 lm bulb and then a 100 W 2360 lm bulb. Though they both emit the same energy, the radiometer spun about 30% faster under the 2360 lm.
Why is this? I was thinking maybe this was because visible light is absorbed faster than the infrared, but don't know for sure.
Thanks,
