To construct a ray diagram, we use two rays which are so chosen that it is easy to know their directions after reflection from the mirror. List two such rays and state the path of these rays after reflection in case of concave mirrors. Use these two rays and draw ray diagram to locate the image of an object placed between pole and focus of a concave mirror.

Explanation

To construct a ray diagram for a concave mirror when an object is placed between the pole (P) and the focus (F), we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Concave Mirror:**
- Draw a concave mirror with its principal axis.
- Mark the pole (P), the focus (F), and the center of curvature (C) on the principal axis. The distance from P to F is the focal length (f), and the distance from P to C is twice the focal length (2f).
