waves vocab #1

science vocab

TermDefinition
amplitude the distance from rest to crest or rest to trough. The larger the amplitude of a wave the more energy the wave has.
compression to push something together (like springs on a slinky in longitudinal wave demo)
crest high point of a wave
frequency the number of complete waves that pass a given point in a certain amount of time. The rate of something that repeats over an over.
KE the energy of motion
longitudinal wave this is a wave that moves a medium parallel (in the direction) to the direction the wave is traveling (ex - slinky when pushing directly into it)
node zero amplitude. The point where the wave crosses its resting point
pulse short bursts that travel as a wave
reflection the bouncing back of a wave when it hits a surface it can't pass through
transverse wave a wave that moves the medium in a direction perpendicular to the direction the wave is traveling (ex - slinky moving the slinky left to right as person holds the other end)
trough low point of a wave
velocity speed in a given direction (ex - 50 mph north)
wave a disturbance that transfers energy from one place to another
wavelength the distance from crest to crest or trough to trough of a wave

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.
