Final answer:
Interference is used to quantify disparities in wave patterns by analyzing the separation between neighboring peaks or calculating the ratio of capacity factors.
Step-by-step explanation:
Interference is used to quantify the disparities in wave patterns. When waves pass through a set of openings with small spacing and widths, interference patterns are formed. By analyzing these patterns, we can measure the differences or disparities from interference. This can be done by examining the separation between neighboring peaks or by calculating the ratio of capacity factors.
