"Poor" is really a woosy adjective.
If you're willing to express the size of the objective mirror in terms of wavelengths instead of
inches or meters or yards, then a radio telescope and an optical telescope with equal diameters
have equal resolving powers.
The familiar difference in their dimensions is simply the obvious consequence of the difference
in the wavelength of the signals they happen to be looking at. The shortest radio waves are
something like 2,000 times as long as the longest light waves.
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
To have better resolving power, and a much clearer image.
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.
Earth's atmosphere does not limit a telescope's resolving power.
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.

1) light-gethering power, 2) resolving power, and 3) magnifying power
Earth's atmosphere does not limit a telescope's resolving power.
The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
Radio telescopes allow us to see things that can't be seen in visible light. And vice versa, optical telescopes can show things that are not visible in radio telescopes. So, the information from both kinds of telescopes really complements each other.

No
the resolving power of light microscope is 0.2 micrometr
Resolving power of microscope is inversely related to the wavelength of the light used. So shorter the wavelength, greater the resolving power.
