Explanation

To draw a labeled ray diagram showing the formation of an image by a refracting telescope when the final image lies at infinity, follow these steps:

### Step-by-Step Solution:

1. **Draw the Objective Lens**: Start by drawing a convex lens, which represents the objective lens of the refracting telescope. Label it as "Objective Lens".

2. **Indicate the Focal Point of the Objective Lens**: Mark the focal point (F₀) on one side of the lens. This point is where parallel rays of light converge after passing through the lens.
