Best Objective for Astronomical Telescope – Rankers Physics

Lens Makers Formula/ Len's Formula: Practice Problem & Solution

A lens of large focal length and large aperture is best suited as an objective of an astronomical telescope since
A large aperture contributes to the quality and visibility of the images.
A large area of the objective ensures better light gathering power.
A large aperture provides a better resolution.
All of the above

Solution Explained:

To solve this problem, we apply the core principles of Lens Makers Formula/ Len's Formula. Understanding the underlying formula is key to arriving at the correct answer below:

A larger aperture lens collects more light (better visibility and brightness), has a higher resolving power (better resolution), and hence satisfies all specified criteria.
