Phys:Wave Properties

TEKS P.8A, P.8B, P.8C

TermDefinition
wave a disturbance that travels through a medium, transferring energy without transporting matter
harmonic motion periodic motion where an object oscillates around an equilibrium point; motion that repeats itself over regular intervals of time
transverse wave oscillations or vibrations of the particles in the medium are perpendicular to the direction of the wave's motion
longitudinal wave the particles of the medium vibrate in a direction parallel to the direction of the wave's travel
wave velocity the speed at which a wave propagates (moves) through a medium
frequency the number of wave cycles that pass a given point in space per unit of time
hertz the unit of measurement for frequency
period the time it takes for one complete cycle or oscillation of a repetitive motion
amplitude the maximum displacement of a wave or oscillating system from its equilibrium or resting position
wavelength distance between corresponding points of two consecutive waves
electromagnetic waves a form of radiation that travel though the universe. They are formed when an electric field couples with a magnetic field
electromagnetic spectrum the full range of electromagnetic radiation, organized by frequency or wavelength
medium a substance through which waves or energy can travel
crest the highest point of a wave, representing the maximum displacement of the medium from its rest position
trough the lowest point of a wave, represents the maximum negative displacement of the wave from its rest position
compression a region within a longitudinal wave where particles are closely packed together
rarefaction a region where the particles of the medium are spread out

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.
