Answer 1

The Müller-Lyer illusion leads us to perceive lines with outward-pointing arrowheads as being farther away from us, which is an interpretation based on depth perception and context. option c.

Step-by-step explanation:

According to the Müller-Lyer illusion, we tend to see lines with outward-pointing arrowheads as being farther away from us. This optical illusion occurs because of the way our brains interpret the visual cues provided by the arrowheads on the lines. The illusion suggests that the line with the outward-pointing arrowheads looks longer than when the arrowheads are pointing inward, although both lines are the same length. This effect is rooted in our perception of depth and the context in which the lines are presented.

The Müller-Lyer illusion can be applied to our understanding of how we perceive images through lenses. For instance, a diverging lens creates a virtual image that is upright and appears farther away from the lens than the object. This is similar to how the outward-pointing arrowheads in the illusion make the line appear farther away. Our brains are processing the context, just as the lens of the eye converges light rays to form a real image on the retina, making the distant objects appear clearer.
