Explain the process which enables us to perceive the motion in the cartoon film.

Hint : The process name is Persistence of vision which enables us to perceive motion in the cartoon film. The persistence of vision is the phenomenon hence the image of the object is retained on the retina for a very short period of time. The persistence of vision traditionally refers to the Optical illusion.

Complete step-by-step solution:
The term persistence of vision can be explained by motion perception in optical toys. In the cartoon film, we can see the projection of the static pictures through the screen in a particular order.
Generally, these static pictures are always shown in $24$ pictures per second.
here one after giving the perception of movement. The persistence of vision can be described as phenomena in which we can perceive motion in the case of cartoon film.
The image will retain on the retina for a very short period of time as a result of the persistence of vision. The image remains for $\dfrac{1}{{16}}$ th of the second on the retina if the image in our eyes is flashed faster than the picture appears to us to be Moving.

Note: The Persistence of vision is, the human eye and brain can only process $10$ to $12$ separate images per second, retaining an image for up to a fifteenth of a second If an upcoming image replaces it in this period of time it will create the illusion of continuity
The persistence of vision helps the animators to create smooth animations in a very efficient way by showing limited frames that create a sense of motion.
