# Waves

What is a wave? A disturbance that transfers energy.
What is the medium? The material that a wave travels through.
What is a transverse wave? Particles that move perpendicularly to the direction the wave travels.
What is the crest? The highest point of a transverse wave.
What is the trough? The lowest point of a transverse wave.
What is a longitudinal wave? Particles that move parallel (Back and Forth) in the same direction that the wave travels.
What is compression? Particles squeezed together.
What is rarefaction? Particles stretched out.
What is amplitude? The measure of how far energy a wave carries.
What is wavelength? The distance from any point on a wave to the next identical point on the same wave.
How do you calculate wave speed? wave speed= wave length x frequency
What is frequency The number of waves that pass a point in a given amount of time.
If your time is is 4 cm/s and work is 52 joules, what is the time? 13s = 52j / 4cm
if the frequency is 50Hz and the wavelength was 5cm, what is the speed? 250= 50hz x 5cm
What is a mechanical wave? Waves that require a medium.
What is an electromagnetic wave? Waves that do not require mediums.
What is force and what do you measure it in? Pusher or pull on an object to change the motion of an object. You measure it in Newtons.
What is work and what do you measure it in? The use of force to move an object. You measure it in Joules.
What is power? The ability to do something or act a certain way.
What is Hertz? The measurement of frequency.
if your force was 20 newtons and work were 100 joules, what was your distance? 100j= 20n x 5cm
What is the formula for work? Work= force x distance.
What is the formula for power? Power= work / time.
Mechanical or electrical waves require medium. Mechanical waves.
The amount of energy in a mechanical wave is it's frequency or amplitude? Amplitude.
A medium or resting position is the material the wave travels through. Medium.

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.
