Explanation:
Detailed explanation-1: -A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.
Detailed explanation-2: -Reflecting telescopes are sometimes called Newtonian telescopes after their inventor Isaac Newton who built the first one in 1668. They use mirrors to collect and focus the light towards the eyepiece. Mirrors are lighter than lenses and they are also easier to shape into a smooth and perfect surface.
Detailed explanation-3: -Hence, concave mirrors are used in a telescope instead of using a plane mirror.
