Waves Vocab

QuestionAnswer
wave transports energy through a medium
oscillation up-and-down motion of a particle
medium an object or substance through which energy is transported
traverse wave particles in the medium oscillate perpendicular to the motion of the wave
longitudinal wave particles in the medium oscillate parallel to the motion of the wave
amplitude distance between equilibrium and the crest/trough
crest position farthest above equilibrium
trough position farthest below equilibrium
equilibrium position of particles when at rest
pulse width distance between particles at equilibrium around pulse
wavelength distance between equivalent points on waves
reflection when a wave hits a boundary and returns in the direction from which it came
fixed-end reflection an end that can't move causes a wave to invert
free-end reflection an end that can move causes a wave to stay the same
transmission when a wave moves from one medium to another. could change speed and wavelength, but not frequency.
interference when waves meet
wave superposition amplitude at every point increase
constructive wave build on each other
destructive wave destroy each other

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.
