science vocab- waves

QuestionAnswer
refraction the bending of a wave caused by a change in its speed as it moves to a different medium
transverse wave in which the matter moves perpendicular to the direction the energy travels
electromagnetic waves waves that do not need a medium to transfer enegy
medium material through which a wave transfers energy
rarefaction less dense region of a longitudinal wave
amplitude measure of energy in a wave
reflection when a wave strikes a barrier and bounces back
longitudinal wave in which the matter in the medium moves parallel to the direction the energy travels
mechanical waves waves that can only travel through a medium
period the amount of time it takes one wavelength to pass a point
interference the ability 2 or more waves to combine and form a new wave
frequency measure of how many wavelengths pass a fixed point each second
diffraction the bending of waves around a barrier
crest highest point of a transverse wave
compression region where the medium is dense in a longitudinal wave
wavelength distance between one point in a wave to the next nearest point just like it
trough lowest point of a transverse wave
wave repeating disturbance that transfers energy through matter or space

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.

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.
