QuestionAnswer
A disturbance that transfers energy from place is called wave
mechanical waves are created when a source of energy causes a medium to move or vibrate
the speed of a wave is its wavelength multiplied by its frequency
the bending of waves due to a change in speed is called diffraction
the bending of waves around the the edge of a barrier is known as refraction
the interaction between two waves that meet is called interference
waves combine to make a wave with larger amplitude in a process called constructive
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 standing wave
what occurs when vibrations traveling through an object match the objects natural frequency resistance
a wave travels through a medium because it passes through particles
mechanical waves are classified according to how they move
frequency is measured in units called hertz or HZ
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
why do you see lighting from a distant storm before you hear thunder because light travels than sound
compressions and rarefactions are characteristic of what type of wave destructive
the distance between two consecutive crests of a wave is called a 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.
