Question

1pt the size of atoms is such that ________.
a. the largest can be seen with the naked eye with careful observation
b. many can be seen with a hand magnifying lens
c. some can be seen with a good classroom light microscope
d. they can only be imaged by equipment that does not use visible light

Explanation:

Atoms are far smaller than the wavelength of visible light, so visible light-based tools like the naked eye, magnifying lenses, or light microscopes cannot resolve them. Only specialized equipment using non-visible light (or other non-optical methods, like electron microscopes which use electron beams instead of visible light) can image atoms.

Answer:

D. they can only be imaged by equipment that does not use visible light
