QuestionAnswer
What is a repetitive motion that transfers energy from one place to another? Wave
True/False Light or sound are examples of waves. True
True/False Waves are vibrations. True
True/False Sound waves always move at the same speed. False
True/False Waves have common characteristics such as wavelength, frequency, and amplitude. True
What is the word for the number of waves passing through a point in a given time? Frequency
What determines the height of a wave. It is half the distance between the peak and a trough? Amplitude
The _____ are the highest points reached by the wave and the _____ are the lowest points reached by the wave. Peaks, Troughs
True/False Both waves on the water surface and sound waves are mechanical waves. True
True/False Mechanical waves need a medium to travel. True
The distance between two peaks of a wave is called what? Wavelength
True/False Waves move matter. False
True/False Waves transport energy. True
The ______ of a wave is the time it takes for an entire wave to pass through a point. Period
In a sound wave a higher frequency makes it sound (Higher/Lower) pitched? Higher
In a sound wave a higher amplitude makes it (Louder/Softer.) Louder
The distance a wave travels in a given time is referred to as the wave's ________. Speed

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.
