Optical telescopes are used primarily because the visible light spectrum aligns closely with the peak sensitivity of the human eye, allowing for direct observation and interpretation of celestial objects. They also benefit from the Earth's atmosphere, which can better transmit visible light than other wavelengths, enabling clearer images. Additionally, many astronomical phenomena, such as star formation and planetary details, are best studied in optical wavelengths, making these telescopes essential for certain observations.

No, a radio telescope is designed to detect radio waves, which have much longer wavelengths than visible light. Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
Mirrors, The Hubble space telescope first had one big shaped mirror, which made the images blury so they sent up astronaughts and replaced it with 4 8.2 meter flat mirrors making the pictures more clear!
Galileo discovered stars by using the telescope?
See things that don't shine in the visible spectrum.
Usually, by using your eye sight, optical telescope, or radio telescope.
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.

Apart from the obvious planets etc in our solar system we can also see back in time

The term optical telescope refers to telescopes that are used to make observations in the visible light spectrum, that the human eye can see. This is in comparison to such things as X ray telescopes, radio telescopes, etc., which are designed to make observations in parts of the electromagnetic spectrum that are invisible to the human eye.
Mirrors are used in a telescope because they bounce images off of them instead of bending images like refracting telescopes. This ensures that the image is focuses. If you were using a refracting telescope (no mirror) the colours would be bent at different times making an unfocused image.
The Amazon River was not discovered by Galileo using a telescope.
