Question

magnifying glass, microscope, telescope: these pieces of equipment all have something in common. this common feature is something they do not share with an electron microscope. what is this feature? a all three produce 3d images. b they all use visible light and glass lenses. c specimens to be viewed must be carefully prepared. d they all have low magnification and low resolution.

Explanation:

• Option A: Magnifying glass and optical microscopes/telescopes don't all produce 3D images; many produce 2D, so A is wrong.
• Option B: Magnifying glass, optical microscope, and telescope use visible light and glass lenses. Electron microscopes use electrons (not visible light) and electromagnetic lenses (not glass), so this is the common feature they don't share with electron microscopes.
• Option C: Magnifying glass doesn't require specimen preparation, while electron microscopes and some optical setups might, so C is wrong.
• Option D: Telescopes and some microscopes can have high magnification/resolution, and electron microscopes have high resolution, so D is wrong.

Answer:

B. They all use visible light and glass lenses.
