The term "illusion" refers to a misperception or misinterpretation of a sensory stimulus, such as the perception of two lines being the same length when they are not. The Müller-Lyer and Ponzo effects are specific types of illusions that involve the misperception of the length of lines, but the general term "illusion" is the best choice to describe this situation. "Delusion" refers to a persistent false belief or idea that is maintained despite evidence to the contrary, which is not applicable in this scenario.
