The lenses used in reflector telescope is the concave lens.
i do not know and i don't really care no ifence
The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g
They both use a parabolic reflector.
The Hubble Space Telescope, or HST, or just the "Hubble" for most folks, is a Ritchey-Chrétien reflector telescope. It has a primary mirror to reflect and focus the incident light. A link is provided below.
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
Yes, or lenses. Called reflector and refractors respectfully.
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.

That telescope you are refering to is called a refracting telescope.
A Cassegrain reflector
it is a reflector telescope
Reflector telescopes are cheaper to make than refractors of the same size than passing through it, only one side of the reflector telescope's Often a secondary mirror is used to redirect the light into a more convenient viewing spot.
Reflector.
The Newtonian Telescope.
The HST is a Cassegrain reflector telescope.
