Transverse Wave mechanical wave that causes particles in matter to move at right angles to the direction the wave travels
Intensity amount of energy a wave carries past a certain area past a certain area each second
Pitch human perception of the frequency of sound
Infrared Wave electromagnetic wave with wavelengths between about one thousandth of a meter and 700 billionths of a meter
Reverberation repeated echoes of sound waves
Wavelength distance between one point on a wave and the nearest point moving with the same speed of direction
Wave disturbance that moves through matter and space and carries energy
Frequency number of wavelengths that pass a given point in one second, measuring in hertz
Refraction change in direction of a wave when it speed as it travels from one material into another

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.
