Answer 2

The answers are as follows:

1. The student is suffering from Myopia due to which he couldn't read the blackboard clearly while sitting on the last bench in the classroom. Moreover the image forms before the retina due to this defect.
2. A convex lens can be used to correct his defect as it will help the image to form on the retina instead of forming before the retina.
3. Elongation of the eye lens and enlargement of the eyeballs are two possible reasons for this defect of vision.
