I don't know if this is the right place to post this question, but you're a clever lot so I'm sure you'll know the answer.
We are all familiar with the illusion of the wheels on a car on television appearing to spin backwards when the car is traveling forward, this being caused by a mismatch of the picture frequency and the wheel's rotational speed.
However this phenomenon can also be observed in the real world, say, when you are looking at the wheel of the car beside you as you drive down the road.
Anyone know what causes this ?
