Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is wave interference?Wave interference is when two or more waves overlap and combine. The resulting wave can be bigger or smaller depending on how they line up. It's like when two friends jump at the same time and make a higher jump.
2. How do constructive and destructive interference happen?When waves line up so their peaks match, they add together and make a bigger wave – that's constructive interference. If a peak meets a dip, they cancel each other out – that's destructive interference. If the waves are exactly opposite, they can cancel completely.

Coherence: The property of waves having a constant phase difference, essential for sustained interference.
Path Difference: The difference in distance traveled by two waves from their source to a point of interference.
Interferogram: The fringe pattern produced by the interference of two or more waves, containing information about the waves.
