Because light can enter a lens from either side, a lens has a focal point on both sides. With mirrors, on the other hand, light only enters from one side, so they only have one focal point. the apex answer:
The centers of curvature of the two sides of the lens The material the lens is made from

What was the two lenses called on the refracting telescope?
The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
What is a barlow lens on a telescope?
A Barlow lens is an accessory used in telescopes to increase the focal length, resulting in magnification of the image. It allows the telescope to achieve higher magnification without needing to switch to a higher power eyepiece. By inserting the Barlow lens between the telescope and eyepiece, it effectively doubles or triples the focal length of the telescope.
Was the telescope created by accident?
The first telescope was invented by Hans Lipperhey , a Dutch lens grinder, in 1609 when he combined two lenses.
How many lenses does a telescope have?
A telescope usually has two lenses: the objective lens, which gathers and focuses light, and the eyepiece lens, which magnifies the focused light for viewing. Some telescopes may have additional lenses for specific functions, such as correcting aberrations or enhancing image quality.
What does the simplest optical telescope contain?
The simplest optical telescope typically consists of two main components: a concave objective lens or mirror that collects light and forms an image, and a smaller eyepiece lens that magnifies and brings the image into focus for the observer. These components come together to allow for viewing distant objects in greater detail by gathering and focusing light.
What are the names of the two converging lenses that are used to make a simple telescope?
1. The Objective Lens. 2. The Eyepiece Lens.

The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
What type of telescope uses two lenses?
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.

What tool besides a telescope in a science lab uses two convex lens?
Microscope
What uses two lens and mirror?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.

I asked this question before but I didn't get the right answer I want to know how your eyes are similar to a telescope and how they are different I don't want to know about binoculars?
i can understand when you don't get the answer you want so here is the answer: our eye works simillar to telescopes because telescope uses convex lens to create a perfect magnified focused image and the eye too uses convex lens to focus the image however our eye rarely uses the lens to magnify image our eye's lens can autofocus near and far objects which is known as eye accomodation with bulging and stretching of eye's organic lens; decreasing and increasing the focal length of the eye lens whereas this flexible lens is not used in telescope instead two lenses are used.
