Physical Science 10

chapter 10

QuestionAnswer
A repeating disturbance or movement that transfers evergy through matter or space is a? Wave
Matter in which a wave travels is called a? Medium
Waves that can travel only through matter are called? Mechanical Waves
A wave for which the matter in the medium moves back and forth at right angles to the direction the wave travels and has crests and troughs is called a? Transverse Wave
A wave for which the matter in the medium moves back and forth along the direction that the wave travels is called a? Compressional Wave
A combination of a compressional and a transverse wave is a? Seismic Wave
Alternating high points are called? Crests
Low points are called? Troughs
Regions where the medium becomes crowded together and more dense is a? Compression
A less dense region of a compressional wave is a? Rarefaction
The distance between one point on a wave and the nearest point just like it is a? Wavelength
The number of wavelengths that pass a fixed point each second is? Frequency
What expresses frequency? Hertz
The amount of time it takes one wavelength to pass a point is a? Period
An example of this type of wave interaction or behavior could be a marching band you can hear but cannot see because it is around the corner. Diffraction
This wave behavior appears when a wave hits another object and bounces off (like an echo) Reflection
An example of this type of interference might be 20 people singing in choir to produce a louder sound when the crests combine. Echo
This wave travels at right angles to the direction the wave travels like a rope or water that has an up and down motion. Standing Wave
What do waves carry? Energy
All waves are produced by something that? Vibrates
In a mechanical wave a medium can be? Solid, Liquid, and Gas
The medium for sound waves is? Air
The medium for ocean waves is? Water
Do all waves need a medium? No
What type of waves are sound waves? Compressional
Not all waves need a medium to travel through an example of this is? Light Waves

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.
