Question

1. how is a refracting telescope similar to a compound microscope? (1 point)

both instruments have a convex objective lens and a convex eyepiece lens.
both instruments are used to enlarge small objects.
both instruments use mirrors to gather light and lenses to enlarge images.

Explanation:

A refracting telescope has a convex objective lens that gathers light and forms an image, and a convex eyepiece that magnifies this image. A compound microscope also has a convex objective lens (to form a magnified real image of a small object) and a convex eyepiece (to further magnify the image formed by the objective). The second option is wrong because telescopes are for viewing distant objects (not necessarily small in size, just distant), not enlarging small objects like microscopes. The third option is wrong as refracting telescopes don't use mirrors (reflecting telescopes do), and microscopes also don't use mirrors in the way described (they use lenses).

Answer:

Both instruments have a convex objective lens and a convex eyepiece lens.
