A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]

Is the difference between a refracting telescope and a reflecting telescope?
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
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.
Did Galileo invent the reflecting or the refracting telescope?
no

What other things were developed using the refracting telescope design?
the reflecting telescope was!!
Why did Isaac Newton invent the telescope?
Newton did not invent the telescope, he invented the reflecting telescope. The reflecting telescope was a major improvement over the distorting refracting telescope.
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
What are some of the advantages of reflecting telescopes over refracting telescopes?
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
Why are reflecting telescope and refracting telescope considered as optical telescope?
"Optical", in this case, simply means that they work with light.
What is another type of telescope other than reflecting and refracting telescopes?
Radio
How is a radio telescope similar to a refracting telescope and a reflecting telescope?
They all collect and focus light and other forms of electromagnetic radation.
Why are most modern telescopes reflecting telescopes?
A reflecting telescope is much easier to build than a refracting telescope and consequently is much less expensive. A reflecting telescope uses a concave mirror to collect and concentrate starlight and send it to your eye, whereas a refracting telescope uses a series of lenses to do the same thing. Optical quality lenses are much more expensive (and heavier) than a well-made mirror. For a given amount of money, much larger reflecting telescope can be built than a refracting. For very large telescopes, the lenses needed would be enormous and next to impossible to make optically perfect. Consequently, most telescopes are reflecting.
