Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
Both reflecting and refracting telescopes are designed to gather and focus light to create images of distant objects in space. Reflecting telescopes use mirrors to reflect and concentrate light, while refracting telescopes use lenses to refract and focus light.
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
The reflecting telescope deals with light. It uses mirrors to gather and focus incoming light from distant celestial objects for observation. Sound waves are not used in reflecting telescopes.
Radio telescopes, refracting telescopes, and reflecting telescopes all use mirrors or lenses to collect and focus incoming electromagnetic radiation. The main difference is the wavelength of the radiation they are designed to study – radio telescopes focus on radio waves, refracting telescopes focus on visible light, and reflecting telescopes focus on a variety of wavelengths including visible light, ultraviolet, and infrared.

Not sure. Please check an encyclopedia or your teacher knows it.
One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.

Ah, a refracting telescope is a wonderful invention! It works by using a lens to bend or refract light, helping us see objects in the distance with more clarity. Unlike other types of telescopes, like reflectors or catadioptrics, refracting telescopes use lenses instead of mirrors to gather and focus light. Remember, there's no right or wrong choice when it comes to telescopes – each one has its unique beauty and purpose!

Radio telescopes use large antennas to gather radio waves by focusing them onto a receiver. The receiver amplifies and converts these radio waves into electrical signals that can be analyzed by scientists to study celestial objects and phenomena in space.
