Draw aray diagram to show the image formation of a distant object by a refracting telescope. Write the expression for its angular magnification in terms of the focal lengths of the lensesused. State the important considerations required to achieve large resolution and their consequent limitations.

Explanation

### Step-by-Step Solution

**Step 1: Draw the Ray Diagram**
1. Start by drawing the two lenses of the refracting telescope: the objective lens (L1) and the eyepiece lens (L2).
2. Position the objective lens (L1) on the left side of the diagram and the eyepiece lens (L2) on the right side.
3. Draw a distant object (O) on the left side, far away from the objective lens.
4. Draw rays from the object O: one ray parallel to the principal axis that passes through the focal point (F1) of the objective lens and another ray that passes through the center of the objective lens.
5. The rays converge to form an image (A'V') on the opposite side of the objective lens.
