A 14 year old student is not able to see clearly the questions written of the black board placed at a distance of 5 m from him.
Draw the diagram to show how this defect can be corrected.

Explanation

To solve the problem of the 14-year-old student who cannot see clearly the questions written on the blackboard placed at a distance of 5 m, we need to understand that this condition is known as myopia or nearsightedness. Myopia occurs when the eye is too long or the cornea is too curved, causing distant objects to appear blurry. The correction for myopia is done using a concave lens.

### Step-by-Step Solution:

1. **Identify the Problem**: The student is unable to see objects clearly at a distance of 5 meters, indicating a myopic condition.

2. **Understanding Myopia**: In myopia, light rays from distant objects converge before they reach the retina. This results in a blurry image of distant objects.
