an oscillation, or repeating back and forth motion, about an equilibrium position. vibration
a disturbance that repeats regularly in space and time and that is transmitted progressively from one place to the next with no actual transport of matter. wave
the time required for a pendulum to make one to and fro swing (single cycle). period
the back and forth vibratory motion of a swinging pendulum. simple harmonic motion
a curse whose shape represents the crests and troughs of a wave, as traced out by a swinging pendulum that drops a trail of sand over a moving conveyor belt. sine curve
one of the places in a wave where the wave is highest or the disturbance is greatest. crest
one of the places in a wave where the wave is lowest, or the disturbance is greatest, in the opposite direction from a crest. trough
the distance from the midpoint to the maximum (crest) of a wave or, equivalently, from the midpoint to the minimum (trough). amplitude
the distance from the top of the crest of a wave to the top of the following crest, or equivalently, the distance between successive identical parts of the wave. wavelength
the number of events per time; measured in hertz (or events per time). Inverse of period frequency
the SI unit of frequency. One Hz is one cycle per second. Hertz
a wave with a vibration at right angles to the direction the wave is traveling. transverse waves
a wave in which the vibratio is in the same direction as that in which the wave is traveling, rather than at right angles to it longitudinal waves
a pattern formed by the overlapping of two or more waves that arrive in a region at the same time interference pattern
addition of two or more waves when wave crests overlap to produce a resulting wave of increased amplitude. constructive interference
combination of waves where crests of one wave overlap troughs of another, resulting in a wave of decreased amplitude. destructive interference
term applied to two waves for which the crest of one wave arrives at a point at the same time that a trough of he second wave arrives. Their effects cancel each other out of phase
term applied to two or more waves whose crest and troughs arrive at a lace at the same time, so that their effects reinforce each other. in phase
wave in which parts of the wave remain stationary and the wave appears not to be traveling. The result of interference between an incident wave and a reflected wave. standing wave
any part of a standing wave that remains stationary. node
the positions on a standing wave where the largest amplitudes occur. antinode
the apparent change in frequency of a wave due to the motion of the source or of the receiver. doppler effect
an increase in the measured frequency of light from an approaching source; called this because the apparent increase is toward the high frequency, or blue, end of the color spectrum. also occurs when an observer approaches a source blue shift
a decrease in the measured frequency of light or other radiation from a receding source; called this because the decrease is toward the low frequency, or red end of the color spectrum. red shift
the V-shaped wave produced by an object moving on a liquid surface faster then wave speed. bow wave
a cone shaped wave produced by an object moving at supersonic speed through a fluid. shock wave
the sharp crack heard when the shock wave that sweeps behind a supersonic aircraft reaches the listener. sonic boom

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.
