### science

A disturbance that transfers energy from place to place waves
Mechanical waves are created when a source of energy causes a medium to vibrate
The speed of a wave is is wavelength multiplied by its frequency
The Bending of waves due to a change in speed is called refraction
The interaction between two waves that meet is called interference
The bending of waves around the edge of a barrier is known as diffraction
Waves combine to make a wave with a larger amplitude in a process called constructive interference
What occurs when vibrations traveling through an object match the objects natural frequency resonance
A wave travels through a medium because energy passes from particle to particle
When an incoming wave combines with the reflected 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
Mechanical waves are classified according to how they move
Frequency is measured in Hertz
When a wave hits a surface witch it CANNOT pass through 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 before hearing the thunder? light travels faster than sound
Compressions and rarefactions are characteristics of what kind of wave? Longitudinal
The distance between 2 consecutive crests in 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:

• 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.
