Waves and Sound Wave

TermDefinition
Wave a disturbance caused by energy moving from one location to another through a medium/substance
Energy the strength of a wave, which can increase how far it disturbs the particles it moves through
Medium the matter a wave is moving through. Can be a solid, a liquid, or a gas.
Mechanical Wave a wave that requires a medium to move through
Transverse Wave a wave that vibrates particles perpendicular to the direction the wave travels
Crest The maximum/highest point of a wave
Trough The minimum/lowest point of a wave
Amplitude the “height of a wave” measured from its center to a crest or trough
Wavelength the “length of a wave” measured from crest to crest, or from trough to trough
Frequency The number of waves that pass a fixed point within a second OR how squished together a wave is. The shorter the wavelength the greater the frequency.
Compression Wave a wave that vibrates particles in the same direction the wave travels
Compression The part of a compressional wave where the particles are most pushed together
Rarefaction The part of a compressional wave where the particles are most spread apart
Pitch how high or low a note sounds
Loudness the strength of a sound
Reflection When a wave strikes another object and bounces off. When the wave is a sound wave it produces an echo.
Absorption When a wave strikes another object and is absorbed by the object rather than bouncing off.
Diffraction The bending of waves around a barrier. The wave will move through an opening and expand out beyond it.
Refraction the bending of a wave as it moves from one medium into another.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
