WebbIt has an objective lens that’s 1.02 meters (40 inches) across, and it’s total power is 195x. (The 40 inch telescope at Yerkes Observatory) Reflecting telescopes, on the other hand, don’t use lenses at all. Instead, they use mirrors to focus the light together. In this case, the type of mirror that they use is a concave mirror. Webb13 apr. 2024 · Telescope - It is another remarkable optical instrument. It makes distant objects emerge nearer by using an arrangement of lenses or lenses and curved mirrors that is used to observe the objects by absorption, emission, and reflection of their electromagnetic radiation to furnish a magnified image.
