Waves/Sound

QuestionAnswer
Wave Traveling disturbance that carries energy from one place to another
Vibration Movement that follows the same path over and over again
Medium Material through which a mechanical wave travels
Mechanical Wave Wave that disturbs a medium
Electromagnetic Wave Wave that consists of electric and magnetic fields and does not require a medium to exist
Crest High point of a wave
Trough Low point of a wave
Amplitude Greatest distance from resting position of a wave
Wavelegnth Distance between two consecutive similar points on a wave
Frequency Number of wave that pass a certain point in a given amount of time
Transverse Wave wave in which the motion of the medium is at right angles to the direction of the wave
Longitudinal Wave Wave in which the motion of the medium is parallel to the direction of the wave
Surface wave Wave that consists of a combination of transverse and longitudinal waves and occurs at the surface between two different mediums
Compression Squeezing together
Reflection Bouncing back of waves upon reaching another surface
Refraction Bending of waves around the edge of an obstacle
Interference Interaction of waves that occur at the same place at the same time
Standing wave Wave that does not appear to be moving
Resonant Frequency Frequency at which a standing wave occurs
Pitch Property of sound that depends on frequency
Ultrasonic Sound above the range of human hearing (20,000 Hz)
Infrasonic Sound below the range of human hearing (20 Hz)
Doppler Effect Change in sound or light that occurs whenever there is motion between the source and its observer
Intensity of Sound Amount of energy carried by a wave; indicated by the amplitude of a wave
Acoustics Science of sound and its interactions
Sound Quality Blending of pitches to produce sound; timbre
Timbre Blending of pitches to produce sound; sound quality
Fundamental Tone Note produced at the lowest frequency at which a standing wave occurs
Overtone Tone produced at frequencies higher than the fundamental at which a standing wave occurs

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.
