QuestionAnswer
Wave any disturbance that transmits energy through matter or space
Medium a substance through which a wave can travel
Explain how energy transfers through a medium when a particle vibrates it can pass its energy to a particle next to it. As a result, the second particle will vibrate in a way similar to the first particle.
Describe how sound waves work sound waves require a medium. Sound energy travels by the vibration of particles in liquids, gases, and solids. If there are no particles to vibrate, no sound is possible.
Describe how ocean waves transfer energy they require a medium , which travels through water , and waves on a guitar and cello strings.
Electromagnetic waves waves that don’t require a medium
Give 5 examples of things that operate using electromagnetic waves visible light, microwave ovens, TV and radio signals, and X-rays.
Explain how waves can be classified waves can be classified based on the direction in which the particles of the medium vibrate compared with the direction in which the waves travel.
Describe how transverse waves move they move in a up and down motion
Describe how longitudinal waves move the particles of the medium vibrate back and forth along the path that the wave travels.
Amplitude and drawing the amplitude of a wave is the maximum distance the wave vibrates from its rest position.
Wavelength and drawing the distance between any two adjacent crests or compressions in a series of waves
Frequency and drawing the number of waves produced in a given amount of time
Wave speed and drawing the speed at which a wave travels
Wave speed formula wave speed equals wavelength times frequency
Reflection occurs when a wave bounces back after striking a barrier
Refraction the bending of a wave as it passes at an angle from one medium to another
Diffraction the bending of waves around a barrier or through an opening
Interference the result of two or more waves overlapping

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.
