Definition

A device that measures waves, such as light or sound, by analyzing the interference patterns created when two waves overlap. It is used to determine distances, wavelengths, and other properties of waves.

Example

The scientist used an interferometer to measure the tiny changes in distance caused by gravitational waves.

Conversation

Hey, have you ever heard of an interferometer?

Yeah, I think it's used in physics to measure wavelengths, right?

Exactly! It's fascinating how it can determine such small distances.

I know! It's amazing what technology can do these days.

Synonyms & Antonyms

Root Explanation

Interferometer → It is formed from "inter-" (meaning between) and "ferre" (meaning to carry or bring) and "-meter" (meaning measure). The word describes an instrument that measures the interference of waves, particularly light, by bringing them together in a way that allows for measurement of their differences.

Memory Tip

Think of waves being 'brought together' ('ferre') from 'between' ('inter-') to measure their interference — that's what an interferometer does.
