The objective lenses of two telescope have the same apertures but their focal lengths are in the ration `1 : 2`. Compare the resolving powers of the two telescopes.

Explanation

To compare the resolving powers of the two telescopes, we can follow these steps:

### Step 1: Understand the Concept of Resolving Power
The resolving power (R) of a telescope is defined by the formula:
\[ R = \frac{A}{1.22 \lambda} \]
where:
- \( A \) is the aperture of the telescope,
- \( \lambda \) is the wavelength of light being used.
