Question

A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in the opposite direction of the normal direction and can then be projected onto a satellite or the Moon.

a) True
b) False

Answer 1

False. Telescopes cannot be used to enlarge the diameter of a laser beam or limit diffraction spreading.

Step-by-step explanation:

False. A telescope cannot be used to enlarge the diameter of a laser beam. Telescopes are designed to collect and focus light from distant objects, such as stars, planets, and galaxies. They work by using multiple lenses or mirrors to gather and amplify the incoming light, resulting in a larger and clearer image. However, telescopes are not designed to modify laser beams or limit diffraction spreading.

If the goal is to limit diffraction spreading in a laser beam, optical elements such as lenses or apertures may be used, but a telescope, in its traditional use, is not designed for this specific purpose.
