There are many illusions that trick your mind and perceptions. The illusion is based on relative proportions and positions that trick the viewer into believing one object is longer or shorter than another. An example of this kind of illusion is shown below (taken from Optical Illusion Magic by Michael DiSpezio)
Believe it or not, there are three pairs of lines that are of the same length. Can you guess which ones?
The Answer is: (1) The red and blue lines , (2) The green and yellow lines , and (3) The purple and orange lines
Doesn’t seem true?
This illusion is made up of two important visual tricks. One being the interruption of the line and the placement of the circles. As you can see, when the lines cross through the circles, the lines seem shorter. With an addition of circles at the endpoints, the lines seem longer.
