What is interference and how is it detected using analytical ultracentrifugation (AUC)?

There are two types of interference:

Constructive Interference

When crests/troughs of two waves meet, creating a crest/trough equal to the sum of their amplitudes.

Constructive interference using analytical ultracentrifugation (AUC) Destructive interference with analytical ultracentrifugation (AUC)

Destructive Interference

When the crest of one wave meets the trough of another, cancelling each other out.

Constructive and Destructive Pattern from 2 Slits

If a light source is passed through two parallel slits, it creates constructive and destructive interference in a repeating “fringe” pattern that can be analyzed via AUC.
