Waves Vocab

3. – The highest point of a wave.
5. wave – A wave that appears to stay in one place, formed by two waves moving in opposite directions.
8. interference – When two waves combine to make a bigger wave (amplitudes add).
10. – The way a wave travels through a medium or space.
13. wave – A wave where motion is parallel to the direction the wave travels (back and forth).
14. interference – When two waves combine and cancel each other out (amplitudes subtract).
15. – How many waves pass a point in one second (measured in Hertz, Hz).
16. harmonic motion – A repeating back-and-forth motion around an equilibrium (rest) position.

1. – One complete back-and-forth movement of a wave or object.
2. wave – A wave that needs a medium to travel through (example: sound waves).
4. – The distance between two identical points on a wave (like crest to crest).
6. – The time it takes for one full wave cycle to pass.
7. (waves) – The material or substance that a wave travels through (like air, water, or a rope).
9. – The lowest point of a wave.
11. – The height of a wave from its rest position; shows how much energy the wave has.
12. wave – A wave where motion is perpendicular (up and down) to the direction the wave travels.
