# Waves

TermDefinition
periodic motion repeated motion
equilibrium point midline of wave or periodic motion (rest position)
amplitude maximum displacement from equilibrium
period time it takes to complete one cycle
frequency number of cycles or vibrations
wave disturbance that propagates through material medium or space
mechanical wave a wave that transmit energy through a medium
electromagnetic wave a wave that can transmit energy through a vacuum (no medium required)
longitudinal wave displacement of the wave is parallel to the motion of the wave
transverse wave displacement of the wave is perpendicular to the motion of the wave
medium substance or material that carries a wave
pulse wave single disturbance in a medium
periodic wave repeated disturbance in a medium
wavelength distance it takes for wave to repeat itself
trough the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position
crest the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position
wave speed how fast a wave transmits its energy
reflection return of a wave when it reaches a boundary of a medium
standing wave the result of two waves with the same wavelength, frequency, and amplitude traveling in opposite directions through the same medium
node points along the medium that appear to be standing still during each vibrational cycle; no displacement
antinode points that undergo the maximum displacement during each vibrational cycle
refraction bending of a wave pass from one medium into another; wave changes speed
diffraction the spreading of a wave around a barrier or through an opening
superposition two or more waves passing through the same location at the same time
superposition principle the total displacement due to interference is the sum of the displacements of the individual waves
constructive interference results in a larger amplitude (adds)
destructive interference results in a smaller amplitude (subtracts)
resonance large amplitude waves caused when the frequency of an applied force is equal to the natural frequency of an object
doppler effect the change in frequency due to the relative motion of the wave source and the observer
loudness amplitude of sound wave
pitch frequency of sound wave
beat the interference of sound waves caused by a slight difference in frequency from two sound sources
simple harmonic motion repeated motion, moves around equilibrium point
vibration oscillation occurs about an equilibrium point
compression a region in a longitudinal wave where the particles are closest together
propagate the way a wave travels
fixed boundary end is attached so that it cannot move
free boundary end is not attached so that it can move
interference two or more waves passing through the same location at the same time
restoring force force that brings object back to equilibrium

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.
