The telescope described is an optical telescope. If the primary optic is a mirror, it's a reflector, and it the primary optic is a lens, it's a refractor.
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
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.
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
The lenses used in reflector telescope is the concave lens.
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.
The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.

The eyepiece of the telescope doesn't magnify the object, but it does magnifythe real image of the object that forms at the focus of the primary lens or mirror.

The "objective" lens (as opposed to the eyepiece).
The lenses used in reflector telescope is the concave lens.
A telescope eyepiece usually has 2 lenses in an astronomical telescope, and it is designed to give a magnified view of the virtual image produced at the focal point of the main lens.
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
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.
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.
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.
