Why can chicken wire be used as the surface of the radio telescope?

It reflects some of radio waves. Also the gaps don't matter too much. That's because of the nature of the radio waves, particularly the wavelengths.
In fact there is a large range of wavelengths.
For the shorter wavelengths a "dish" type receiver is needed, with no gaps.

∙ 15y agoThe mesh of chicken wire is about 1 inch across. Radio waves with a wavelength greater than the size of the holes in the mesh will be reflected, so that a chicken wire dish will reflect the radio energy back to the feed horn at the focus of the dish. But because the air molecules are much smaller than the mesh, the wind blows right through the wire without causing much disturbance.
The speed of light is 186,000 miles per second, or 300,000,000 meters per second. The formula is wavelength * frequency = c, where "c" is the symbol for the speed of light. So this gives you a way to calculate the frequency of the radio waves that will be reflected.
One more point; if you need to reflect higher frequencies, you can do this by making the mesh smaller.

Is a telescope used for weather?
An optical telescope cannot be used during cloudy days. Of course, this assumes that the telescope is located somewhere on the Earth's surface and therefore subject to weather. Since clouds obscure the sky - and any heavenly object otherwise visible - the optical telescope will be unable to see anything. A radio telescope, however, can see through clouds, simply because clouds do not block or cause significant interference to radiowaves reaching the Earth's surface from space.

A device used to detect radio waves from objects in the space?
A radio telescope
Is the radio telescope an instrument which measures radiation?
A radio telescope has two basic components, a large radio antenna and a radio receiver. It is used to detect radio-frequency radiation emitted by objects in space.
Which of these is used in a radio telescope?
Nothing on that list is used in a radio telescope.

When could a radio telescope and a light telescope be used together?
They usually ARE used together, because astronomers want to see if there is anything visible at the same place as this bright radio source in the sky.
Why can't a radio telescope be used on a cloudy night?
A radio telescope can be used on a cloudy night, because its signal can move through the clouds and rain mostly unaffected and still gather data.
Instrument used in studying heavenly bodies?
Optical or radio telescope
