Perhaps when you watch a Western cowboy movie, you notice that the wheels of the cart that are moving away from other vehicles are moving forward at first glance and then start rotating backwards before moving normally.
We observe the same phenomenon in a television scene carried by a car-mounted camera in a race car, for example. So that the front tires appear to rotate backwards against the direction of the cart. What is the reason for this unreasonable phenomenon?
The animation appears in the movie as a result of a certain sequence of still images (usually 24 frames per second). The brain works to save images and transmit them sequentially without regard to the simple intervals, so a moving picture of what happens.
However, there is sometimes a defect in this rule according to the shape and movement of the material. Imagine, for example, that you are visualizing an old wheel with internal rays running 24 times a second - this will be a very fast vehicle - you can carry with us for discussion.
You'll find that the twenty-four still images taken in one second will show the wheel in the same position.
Although the vehicle will appear in the film as it moves forward opposite the space around it, the wheels will look fixed. If the wheels turn, to move 23 cycles per second - the vehicle will fail to complete the full cycle in each still image. When the images are broadcast together, the wheels will look like they are rotating backwards.
What are Harmonies ?!
The same thing happens when the wheels spin at a lower speed or a fixed number of cycles per second such as 24-12-6-3-1 This depends, of course, on the number of wheel beams. For example, in the case of a wheel that rotates 12 times per second, each image will show half a cycle, but if the wheel has a parallel and regular number of internal rays, the wheel will appear fixed. If the wheel rotates 3 cycles per second, each fixed image will appear one on eight of the cycle. As long as the number of rays in the wheel is identical, the image will be stationary (such as 8 or 16 beams) and we bring these examples to illustrate the difficulty of rotating the vehicle at 24 cycles per second.
Despite all of the above, these earlier examples rarely last long in the real world. As the vehicle starts out among a number of other vehicles it will be slow moving, and will fail to complete the entire cycle, and thus will appear to be spinning backwards. When the speed of the vehicle gradually increases, it will begin to appear in a state of rotation. Similarly, the image of the TV movie appears animated by highlighting it 25 times a second. This is why it is difficult to take a picture of a television movie. If the flash speed of your camera lens is more than one in 25 seconds, the camera will be able to capture a still image. Another example is that the image of television on other television or electronic monitoring devices will appear permanently through the mismatch of image cycles or movement in each.
The earlier examples of this phenomenon suggest some practical uses and some risks in working life.
Risks:
The light from the neon consists of a reciprocating electric current that appears in separate light pulses. If the source of electricity frequents 50 Hz (or cycle) per second (and this is what is common in most countries of the world) will occur in the Neon hundred beats per second as the current is reciprocal. In most cases, as during a movie, the eye (or brain more accurately) is unaware of what is happening. However, in large factories and plants, where rotors are now used, such as lathes and other types of light, the moving parts of the machine will look like stationary parts for some time, the second. There are great and unfortunate accidents (the big factories have eliminated this problem by using ordinary tungsten lights, because this type continues to glow according to the frequency of the electrical source, which eliminates frequent electrical and optical impulses).
Useful uses:
For example, if we want to check the speed at which something like a musical disc can rotate in a musical instrument, we can use a tool known as a storboscope. It is a light that can be adjusted to produce light within a given frequency.
A storboscope, which flares at 45 times a minute, will make the 45-minute-per-minute musical drum dish appear to be steady, which confirms that it works properly.
