What are some optical illusions?
Can you tell me about some optical illusions?
Sure, there are many different types of optical illusions. One common type is the Müller-Lyer illusion, where two lines of the same length appear to be different lengths due to the addition of arrows on the ends of the lines. Another is the Ponzo illusion, where two lines that are the same length appear to be different lengths due to the addition of converging lines. Have you heard of any others?
