Why do propellers look slow?
Whilst some propellers are comparatively slow there is an effect called the stroboscopic effect, which at certain revolutions, synchronise reflected light from the blades. This fools the eye into believing the propellers are turning much more slowly than they are.
What is stroboscopic movement?
The movements of strobe lights are a classic example of this.
How stroboscopic tachometer works?

Illusion of movement produced by a rapid progression of images?
stroboscopic motion
Where is a stroboscopic tachometer used?
A stroboscope uses a series of flashes to make a fast moving object seem slower. A stroboscopic tachometer has a scale that reads either in revolutions per minute or flashes per minute.
What is stroboscopic light?
A stroboscopic light, or strobe light, is a device which discharges flashes of light which causes moving objects to appear stationary or slow-moving. The flashing light has been known to cause seizures in people who suffer from epilepsy.

Why do wheel rims appear to go in the opposite direction of the tires?
They don't. Or, at least, they don't always. This effect can occur under certain conditions, and has to do with the speed at which the object is rotating and the limits of perception. It's particularly common in movies and TV shows, where the speed at which the camera operates causes a stroboscopic effect, but it can occur in "real life" as well, particularly under certain kinds of lighting such as fluorescent lights.
Why do television monitors have lines rolling up them when filmed?
TV creates the pictures by displaying it line by line - scanning from top to bottom. This scanning is done at a particular frequency. Film cameras shoot multiple shots per second known as frames per second (fps). When the fps and the frequency of any moving object do not match it will cause a stroboscopic effect. This causes effect of the lines scrolling up. A similar effect can be seen in films where it shows the hub caps of a car or the propeller of an airplane which is speeding up. First it goes reverse, slows down to a stop then goes forward.
Why does a wheel rotating appears to rotate in opposite direction?
The stroboscopic effect can cause the image of a wheel (let us say with many spokes) to appear to be turning at a different speed and even backwards.If succeeding images of a wheel with 12 spokes are taken when the wheel has made , say one eleventh of a turn, just less than enough of a portion of a revolution to bring one spoke where another spoke had been previously, the wheel will appear to rotate slowly backwards.
