Question

choose the correct answer
what does the word \frequency\ mean?
how far apart two things are
how often something happens

Explanation:

The word "frequency" in various academic contexts (such as in Physics when referring to wave - related concepts or in Statistics when talking about data occurrence) generally refers to the rate at which an event occurs. The option "how often something happens" aligns with this common understanding. The other option "how far apart two things are" is more related to concepts like distance (in Physics) or measures of dispersion (in Statistics) rather than frequency.

Answer:

how often something happens
