Well, its simple, there are two things that are in common.... both telescopes have a eye peice and a radio telescope doesnt.... theres more to it and the radio telescope looks way diffrent then the regular ones.....
Wow! What a non-answer this person has given! For one thing, radio telescopes look more like satellite dishes than traditional telescopes. Rather than operating on the visible light spectrum as a reflecting or refracting telescope would, radio telescopes gather information from the infrared light spectrum - radiation waves. These radiation waves are collected to form a picture of whatever the radio telescope is looking at. I'm not a scientist; I'm not an astronomy student. I just did a little bit of research that the original answerer obviously didn't do.

How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Why doesnt the surface of a radio telescope have to be as flawless as the surface of a mirror in an optical telescope?
The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.
How does a radio telescope gather radio waves?
Exactly the same way that an optical telescope gathers waves with wavelngths shorter than radio waves: Both the mirror of a reflecting telescope and the 'dish' of a radio telescope are built to have the shape of a 'paraboloid' ... that's the solid shape you get when you spin a parabola around its nose. The paraboloid has the interesting geometric property that anything that comes straight in, parallel to its axis ... whether it's bees, bullets, B-Bs, or electromagnetic waves ... and bounces off the inside of the curve, all winds up at the same point, called the "focus" of the paraboloid. -- The focus is where the film, or the eyepiece, the CCD, or the spectrometer of the reflecting telescope is placed. All the light that hits the whole mirror is concentrated onto it. -- The focus is where the radio receiver of the radio telescope is placed. All the radio waves that hit the entire dish are concentrated onto it. -- The focus is where the little LNB on the end of the arm that sticks out in front of the TV dish on your neighbor's garage is placed. All the microwave waves from the TV satellite that hit the entire dish are concentrated onto it.
What is the base line of a radio telescope array?
The distance between the two antennae that are the farthest apart is the baseline of a radio telescope array..
What is another type of telescope other than reflecting and refracting telescopes?
Radio
How is a radio telescope different from a refracting telescope?
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
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.
Type of telescope?
Different telescopes utilize different parts of the electromagnetic spectrum. Two types of optical telescope are refracting and reflecting. There are also different kinds of radio telescope investigating different bandwidths from the infra red to the untra violet
What kind of telescope focuses light through a transparent lens?
An optical telescope (as distinct from, say, a radio telescope). It's possible that the answer was intended to be "a refracting telescope" but reflecting telescopes use lenses as well.
What are some similarities and differences between refracting and reflecting telescopes?
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]

What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
Does a telescope use a convex lens?
Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.

Is the design of radio telescopes very similar to the design of refracting telescopes?
no, reflecting telescopes.
In what way is a radio telescope like a reflecting telescope?
They both use a parabolic reflector.
