Does an optical telescope and a radio telescope of the same size have the same angular resolution?
no i hate when people just say no
If you wanted a radio telescope to achieve the same angular resolution as a visible-light telescope it would need to be?
much larger.slightly larger.in space. Correct answer is MUCH LARGER. ;-)
What is the size of the smallest feature visible on Jupiter at 4.2 AU The hubble space telescope has an angular resolution of 0.05?
150
How does angular resolution change as observed wavelength gets longer?
For telescopes of the same size: if the wavelength gets longer, the maximum theoretical angular resolution gets larger (i.e., worse).
Why can a Hubble space telescope make very detailed images in visible light?
I assume you mean the Hubble Space Telescope. Such space telescopes benefit from the lack of an atmosphere: there is no atmospheric distortion, which otherwise severely limits the image quality. The lack of an atmosphere also lets such telescopes see in frequencies that don't get down to Earth at all, for example infrared and ultraviolet. There are OTHER space telescopes in orbit that use this benefit to observe x-rays.
How does sensor resolution relate to its angular resolution?
The angular size of the smallest features that the telescope can see ;-)
What components of a telescope will produce the worst angular resolution?
the lens and eye piece
What type of single telescope currently in operation has the highest angular resolution?
Optical
Does an optical telescope and a radio telescope of the same size have the same angular resolution?
no i hate when people just say no
What is the purpose of interferometry?
It allows two or more smaller telescopes to achieve angular resolution of a much larger telescope.

Interferometry uses two or more telescopes to achieve?
a light-collecting area equivalent to that of a much larger telescope.an angular resolution equivalent to that of a much larger telescope.both the light-collecting area and angular resolution of a much larger telescope.Correct answer: an anguar resolution equivalent to that of a much larger telescope. ;-)

Why aren't stars blurry in the night sky?
Stars are very far away. Eyes just haven't got enough angular resolution. You can help it artificially with technology. Larger the thing, better the angular resolution.
What happens when you increase the diameter of a telescope?
Specifically if you increase the diameter of the main lens, or of the main mirror (depending on the type of the telescope), you'll be able to observe dimmer objects (stars, planets, etc.). Also, the telescope's resolving power (angular resolution) improves with a bigger mirror/lens. For example, with a bigger mirror/lens you'll be able to distinguish two stars that are closer together as separate objects.
