How A Telescope Works Diagram. Parallel light rays enter from the left pass through the objective lens come to a focus at the focal plane and exit through the eyepiece lensfigure. The objective lens gathers the light and bends or refracts it.
Most telescopes and all large telescopes work by using curved. How they work. The tube also helps to keeps out dust moisture and light that would interfere with forming a good image.
The shape of the mirror or lens in a telescope concentrates light.
Most telescopes and all large telescopes work by using curved. Parallel light rays enter from the left pass through the objective lens come to a focus at the focal plane and exit through the eyepiece lensfigure. The first lens refracts light from a distant object by bending it and makes a virtual image of the object closer to your eye than its real position. The tube also helps to keeps out dust moisture and light that would interfere with forming a good image.
