Chap10: Waves

QuestionAnswer
The least dense regions of compressional wave. rarefaction
The process by which an object is made to vibrate by absorbing energy as its natural frequencies. resonance
Distance between one point on a wave to the nearest point just like it on another wave. wavelength
Occurs when two or more waves overlap and combine to form a new wave. interference
A wave for which the matter in the medium moves back and forth along the direction that the wave travels. compressional wave
A repeating disturbance of movement that transfers energy through matter or space. wave
The number of wavelengths that pass a fixed point each second, is expressed in hertz. frequency
The bending of a wave as it changes speed in moving from one medium to another. refraction
A wave pattern that forms when waves equal in wavelengths and amplitude, but travel in opposite directions continually interfere with each other. standing wave
The lowest points on a transverse wave. trough
A wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels. transverse wave
The amount of time it takes a wavelength to pass a fixed point in seconds. period
The bending of waves around an obstacle; can also occur when waves pass through a narrow opening. diffraction

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.
