FLASHCARD QUESTION
Front
Vibration Noun
[vy-bray-shun]
Back
Vibration
A repeating back-and-forth or up-and-down pattern of motion that is the source of all sound energy.
Example: Sound waves are shown as vibrations in air molecules, illustrating how sound energy is produced.
2.
FLASHCARD QUESTION
Front
Sound Wave Noun
[sound wayv]
Back
Sound Wave
An energy pulse created by a vibrating source that travels through a substance, or medium, such as air.
Example: The image shows a sound wave with labeled compressions and rarefactions, demonstrating how sound travels through air.

FLASHCARD QUESTION
Front
Medium Noun
[mee-dee-um]
Back
Medium
A substance, such as a solid, liquid, or gas, through which a wave can travel and transfer energy.
Example: Sound waves travel through air, showing how a medium allows energy transfer.

FLASHCARD QUESTION
Front
Mechanical Wave Noun
[muh-kan-i-kuhl wayv]
Back
Mechanical Wave
A type of wave, such as a sound wave, that requires a medium in order to transfer its energy.
Example: This diagram shows a mechanical wave, like a water wave, labeling its highest point (crest), lowest point (trough), and its length (wavelength).
5.
FLASHCARD QUESTION
Front
Compression Wave Noun
[kuhm-presh-un wayv]
Back
Compression Wave
A wave where medium particles move back and forth in the same direction the wave travels, also called a longitudinal wave.
Example: A spring being compressed and released shows how particles move in a compression wave.

FLASHCARD QUESTION
Front
Amplitude Noun
[am-pli-tood]
Back
Amplitude
The property of a wave that indicates its intensity or energy, which corresponds to the volume of a sound.
Example: The image shows amplitude as the height of a wave from the center line, illustrating wave intensity.
7.
FLASHCARD QUESTION
Front
Wavelength Noun
[wayv-length]
Back
Wavelength
The distance between two identical points on consecutive waves, which is related to the pitch of a sound.
Example: The image shows wavelength as the distance between two crests on a wave.
