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 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.
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.
Yes, a radio telescope is an instrument specifically designed to detect and measure radio waves emitted by celestial objects in space. It is used to study and observe radio emissions from various astronomical sources, providing valuable information about the universe.
