Define magnifying power and resolving power of a telescope.

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Magnifying Power:**
- Magnifying power of a telescope is defined as the ratio of the angle subtended at the eye by the image formed by the telescope to the angle subtended at the unaided eye by the object being observed.
- Mathematically, it can be expressed as:
\[ \text{Magnifying Power} = \frac{\theta_i}{\theta_o} \]
