QuestionAnswer
The matter through which a wave travels. medium
Waves that require a medium. mechanical waves
why light waves are called so. Electromagnetic waves
A disturbance that carries energy through matter or space. wave
waves in which the motion of the particles is perpendicular to the motion of the waves as a whole. transverse Wave
waves that cause the particles in a medium to vibrate parallel to the direction of a wave. longitudinal waves
the highest points of a transverse wave crests
The lowest parts of a transverse wave troughs
the greatest distance that particles are displayed from their normal resting postions. amplitude
the distance from one crest of a wave to the next crest. wavelength
the time required for one fall wavelegth of a wave to pass a certain point. period
the number of full wavelengths. frequency
The change in the observed frequency of a wave resulting from the motion of the source or observer. Doppler Effect
the bending of waves as they pass an edge. diffraction
is simply the bouncing back of a wave when it meets a surface or boundary. reflection
this time, the waves are bending refraction
when several waves are in the same location, waves combine to produce a single, new wave that is different from the original waves. interference
the result is a wave whose amplitude is the same of the amplitudes of the two individual waves. constructive interference
when the crest of one wave meets the trough of another wave, the resulting wave has a smaller amplitude than the larger of the two waves. destructive interference
can form when a wave is reflected at the boundary of a medium. standing waves

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.
