Waves

TermDefinition
wave a disturbance involving the transfer of energy from one place to another.
energy the ability to do work
medium the material through which a wave travels
mechanical wave waves that require a medium to travel
vibration a repeated back and forth or up and down motion
transverse wave a wave that vibrates the medium at right angles, or perpendicular to the direction the wave travels
crest a high point on a transverse wave
trough a low point on a transverse wave
longitudinal wave vibrates the medium in the same direction the wave is traveling
compression an area where the coils are close together
rarefaction an area where the coils are spread out
amplitude the maximum distance the medium vibrates from the rest position
wavelength the distance between two corresponding parts of a wave
frequency the number of waves that pass a given point in a certain amount of time
hertz frequency is measured in this unit
reflection when a wave hits a surface that it cannot pass through it and it bounces back
refraction when a wave enters a different medium at an angle causing the speed of the wave to change . The wave will bend.
diffraction when waves bend around barriers or through an opening in a barrier
interference the interaction of waves that meet
constructive interference interference in which waves combine to form a wave with a larger amplitude and any individual wave's amplitude
destructive interference interference in which two waves combine to form a wave with a smaller amplitude than either original wave had
standing wave a wave that appears to be standing still even though it is two waves passing through each other
resonance increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency

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.
