### Step-by-Step Solution 1. **Understanding the Lens**: A concave lens is a diverging lens that always forms a virtual image. It has two focal points (F) on either side of the lens and an optical center (O). 2. **Drawing the Ray Diagram**: - Draw a concave lens in the center of your diagram. Mark the optical center (O) and the two focal points (F) on either side of the lens. - Draw a horizontal line through the center of the lens to represent the principal axis. ...
