Why the car wheel in the TV looks to turn against the turn
Fast, windy, and dusty, so it looks anti
This internal reason, and the "visual stay" about it! When our human eyes are watching fast-moving objects, even if the image seen in front has disappeared, the human eye can continue to retain 0.1-0.4 seconds or so, which is "visual stay." It is because of this feature of the human eye, coupled with the "frequency effect", high-speed rotation of the wheel "spoke" after 0.1 seconds after the location just in front of the position of 0.1 seconds, then the wheel in our eyes It seems to be turning backwards.
Mainly "frequency effect" at play. This phenomenon usually appears in the film, television, or night exchange lights. When the car is high speed, the wheel frequency is higher than the light frequency, the wheel in our human eye will show a backward turn of the illusion, in fact it is still flying forward. In the case of wheel frequency and light frequency equal, there will be a more rare phenomenon, then the rapid progress of the car wheel as if there is no rotation, still there.
