# CRPhysicsCh11Vocab

vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium simple harmonic motion
the maximum displacement from equilibrium amplitude
the time that it takes a complete cycle to occur period
the number of cycles or vibrations per unit of time frequency
a physical environment through which a disturbance can travel medium
a wave that requires a medium through which to travel mechanical wave
a wave whose particles vibrate perpendicularly to the direction the wave is traveling transverse wave
the highest point above the equilibrium position crest
the lowest point below the equilibrium position trough
the distance between two adjacent similar points of a wave, such as from crest to crest or from trough to trough wavelength
a wave whose particles vibrate parallel to the direction the wave is traveling longitudinal wave
a superposition of two or more waves in which individual displacements on the same side of the equilibrium position are added together to form the resultant wave constructive interference
a superposition of two or more waves in which individual displacements on opposite sides of the equilibrium position are added together to form the resultant wave destructive interference
a wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere standing wave
a point in a standing wave that maintains zero displacement node
a point in a standing wave halfway between two nodes, at which the largest displacement occurs antinode

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
