waves and what they do

QuestionAnswer
A disturbance that transfers energy from place to place is called a wave
The speed of a wave is its wavelength multiplied by it's frequency
The bending of waves due to a change in speed is called refraction
The bending of waves around the edge of a barrier is known as diffraction
The interaction between two waves that meet is called interference
Waves combine to make a wave with a larger amplitude in a process called constructive interference
Mechanical waves are created when a source of energy causes a medium to have a temporarily displacement in particles.
When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still, the result is A standing wave
What occurs when vibrations traveling through an object match the object’s natural frequency? Resonance occurs
How do mechanical waves travel through a medium? Particles of the medium vibrate in place and pass the energy to adjacent particles.
Mechanical waves are classified according to whether they are transverse or longitudinal
Frequency is measured in units called Hertz
When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes reflection
Waves combine to produce a smaller or zero-amplitude wave in a process called destructive interference
Why do you see lightning from a distant storm before you hear thunder? Light travels faster than sound.
Compression's and rarefaction are characteristic of what type of wave? Longitudinal wave
The distance between two consecutive crests of a wave is called the The distance between two consecutive crests of a wave is called the wavelength

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.
