Question

spectrum
\the spectrum lays out every type of light, in order of frequency and wavelength.\
read the quote. what is the meaning of spectrum as it is used in this context?
a a fullness or abundance of something
b an assembly of parts of a machine
c a range of something arranged in a particular order
d a group of objects gathered together

Explanation:

To determine the meaning of "spectrum" in the quote, we analyze the context: "lays out every type of light, in order of frequency and wavelength". Option A refers to abundance, which doesn't match the ordered arrangement. Option B is about machine parts, irrelevant. Option C describes a range arranged in order, matching the quote's description of light types ordered by frequency/wavelength. Option D is about gathering objects, not ordering. So C is correct.

Answer:

C. a range of something arranged in a particular order
