Question

Explain the basic differences between the construction and working of a telescope and a microscope.

Answer 1

Hint: A microscope requires the subject to be near to the lens, whereas subjects are very far from the lens as in a telescope. Consider the telescope and microscope layout to respond to the difference between them.

Complete Step-by-Step solution:
A basic operating telescope just requires a pair of lenses placed in a tube. The front lens, identified as the objective, focuses on an image; the back lens, identified as the eyepiece, amplifies the image. While it can seem like a primitive tool, the fundamental operating concepts of more efficient astronomical instruments are perfectly explained by a simple telescope.
The microscope consists of two lenses in the standard microscope configuration: the objective as well as the eye-piece. Usually, the focal length is kept less than 40mm or up to a few mm as the nature of this lens should be converging also the eyepiece lens is also just a converging lens with a focal length of between 50 and 15 mm generally.
Since telescopes display large objects (faraway bodies, stars, and planets or other celestial bodies) their objective lens creates a smaller representation of the actual image. But microscopes display very small objects, and their objective lens produces a broader perspective of the actual image.

Note: Microscopes and telescopes function similarly by letting people view objects not visible to the naked eye. However, telescopes are designed to view distant, faint objects and as such have larger lens diameters, as well as longer focal lengths and changeable eyepieces. lens diameters, as well as longer focal lengths and changeable eyepieces.
