wave properties

General Wave Properties

TermDefinition
Wave a transfer of energy from one point to another via a traveling disturbance
wavelength distance from successive crest to crest or trough to trough. It is measure in meters.
crest the highest point of a wavelength
trough the lowest point of wavelength
frequency number of waves passing by per second. It is measured in hertz.
amplitude the maximum displacement of the wave. it is the distance from the middle of the wave to the crest
mechanical waves waves that are produced by a source of oscillations and required a medium for the energy to move. Some examples are sound waves, water waves and stadium waves.
electromagnetic waves waves that are produced by the vibration of charged particles and does require a medium so energy can travel through empty space.
medium substance that waves travel through
transverse waves waves that travel perpendicular to direction of motion.
longitudinal waves waves that travel parallel to the direction of motion. This is done by the compressions and rarefactions in the medium that they are traveling in.
Reflection waves bounce off a material and goes in a new direction
refraction wave passes through a material and bends. Think contact lens.
Diffraction waves bends around or goes through a hole in a material
Absorption wave is absorbed by a material and may disappear. An example is sound proofing material
constructive interference waves add up and build up a larger wave of higher amplitude
destructive interference waves combine and make a wave of smaller amplitude

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.
