Chpt 12 vocab for final

TermDefinition
Periodic Motion motion that repeats at a constant rate
Restoring Force acts to restore the system to its rest position
Damping the effect of friction on periodic motion
Resonance when an outside force adds energy to the system
Interference when two or more waves meet at the same point
Longitudinal Waves individual particles vibrate in the same direction as the wave
Transverse Waves individual particles vibrate at right angles to the direction of the wave
Cycle each repeated motion
Constructive Interference if waves meet crest-to-crest the wave increases in size at the point where they meet, and constructive interference has occured
Deconstructive Interference if two waves meet crest-to-trough, the waves disappear or are reduced at the point where they meet
Pendulum a mass connected to a string
Spring an oscillating system
Wavelength the distance between corresponding parts of two consecutive waves
Amplitude the maximum displacement from the rest position
Foucault Pendulum gives direct evidence that earth turns on its axis
Period Time/seconds
Crest the highest point of a wave
Trough the lowest point of a wave
Diffraction light bending
Refraction when a wave moves from one medium to another of a different density
Reflection when waves bounce off a surface
Beat wave which occurs when slightly out-of-phase waves meet
Doppler Effect the perceived difference in received frequency compared to the frequency of a wave source due to the relative motion of the observer and the source
Vibration a short, rapid movement
Oscillation a long, slow movement
Frequency Cycles/second; Hertz; Rate
Rest Position Midway between the crest and a trough of a wave
Wave Height distance from crest down; crest to trough

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.
