FLASHCARD QUESTION
Front
Incident Wave Noun
[in-si-dent weyv]
Back
Incident Wave
The initial wave pulse that travels through a medium and strikes a boundary with another medium.
Example: This diagram shows a wave traveling along a spring toward a wall. This initial wave, before it hits the boundary, is the incident wave.
2.
FLASHCARD QUESTION
Front
Transmitted Wave Noun
[trans-mit-ed weyv]
Back
Transmitted Wave
The portion of a wave pulse that continues to travel into a new medium after striking a boundary.
Example: A light wave passes from air into a glass of water, showing how the wave is transmitted, or continues to travel, through the new material.
3.
FLASHCARD QUESTION
Front
Reflected Wave Noun
[ri-flek-ted weyv]
Back
Reflected Wave
The wave pulse that bounces backward into the original medium after striking a boundary between two media.
Example: This diagram shows a light wave from a flashlight, called the incident ray, hitting a mirror and bouncing off as a reflected wave.

FLASHCARD QUESTION
Front
Principle of Superposition Noun
[prin-suh-puhl uhv soo-per-puh-zish-uhn]
Back
Principle of Superposition
The rule stating that the total displacement of a medium from multiple waves is the algebraic sum of individual wave displacements.
Example: When two waves with aligned crests and troughs overlap, their amplitudes add together, creating a new wave with a larger amplitude.
5.
FLASHCARD QUESTION
Front
Interference Noun
[in-ter-feer-uhns]
Back
Interference
The phenomenon occurring when two or more waves superpose to form a resultant wave of a different amplitude.
Example: When waves overlap, they interfere. Constructive interference makes a bigger wave, while destructive interference makes a smaller wave or cancels it out completely.
6.
FLASHCARD QUESTION
Front
Destructive Interference Noun
[dih-struhk-tiv in-ter-feer-uhns]
Back
Destructive Interference
A type of interference where waves with opposite displacements combine, resulting in a wave of lesser amplitude.
Example: When waves from two sources overlap, their crests and troughs can cancel each other out at specific points, resulting in destructive interference.
7.
FLASHCARD QUESTION
Front
Constructive Interference Noun
[kuhn-struhk-tiv in-ter-feer-uhns]
Back
Constructive Interference
A type of interference where wave displacements in the same direction combine, resulting in a wave of greater amplitude.
Example: When waves from two sources overlap, their crests can add together at specific points, creating a wave with a larger amplitude. This is constructive interference.
