1 Our brain interprets inverted images formed on the retina

1. Our brain interprets inverted images formed on the retina as being upright. Assume that the brain becomes capable of interpreting an upright image as an upright position of an object. A diverging lens forms images that are upright and reduced in size. Does this mean that the focusing system of an eye could have been successfully replaced by a diverging lens? Explain.

Solution

Diverging lense form images upright and smaller in size compare to object but image formed by diverging lense is virtual whereas image formed by eye is always real. So eye cannot replaced by a diverging lense. If image formed by eye is not real then brain cannot intercept it correctly. So for brain to intercept image must be real so eye cannot be replaced by diverging lense.
