light hits tiny microscopic beads or sattelite dishes or cube corner prisms, then light is reflected back to original light source to create glowing effect.
cuz there diffrent
"Optical", in this case, simply means that they work with light.
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
Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.
It all depends on if the telscope is a refractor, or a reflector. Reflectors have a convex mirror that bends the reflection on to a flat mirror that angles the magnified reflection to the eyepiece. Refractors use to convex lenses that bend the image and light, magnifying the view to the eypiece.
Galileo did not invent the telescope. The Italian physicist and mathematician improved on an existing spyglass design to create a more powerful one: a refracting telescope that he then used to study the night sky.

Refracting telescopes use lenses. Reflecting telescopes use mirrors to reflect things that's why it's called a reflecting telescope. Now back to refracting telescopes, they work exactly like magnifying glasses. It use a convex lens to bend light and bring it into focus, and a concave lens to magnify it.It also does that by directing light beams to meet at a focal point
The Hobby-Eberly Telescope works by refracting light through 1 meter long frames of glass, put together to form the lens, and uses the light to project images of what that light is coming from.
by refracting light
refracting telescopes... :)
Refracting telescopes.
Radio telescopes. I believe the largest INDIVIDUAL radio telescope has a diameter of about 300 meters. Moreover, several of those are often connected to work in unison.
