Define magnifying power and resolving power of a telescope.

Explanation

### Step-by-Step Solution:

1. **Definition of Magnifying Power**:
- The magnifying power of a telescope is defined as the ratio of the angle subtended at the eye by the image produced by the telescope to the angle subtended at the eye by the object being observed when viewed with the naked eye.
- Mathematically, it can be expressed as:
\[ \text{Magnifying Power (M)} = \frac{\theta'}{\theta} \]
