I think the response is shorter (< 10ms). I drove a laser with tone() and pointed it at a photoresistor*, and (via ascii-art graph from analogRead()) can clearly see a 200Hz signal, implying < 2.5ms until a detectable response.Note however that at 32Hz the rise and falloff are much more visible; clearly at 200Hz the photoresistor (or some part of …
