Waves

TermDefinition
Wave A disturbance that moves through matter or space.
Transverse Wave a wave vibrating at right angles to the direction of its propagation.
Compressional Wave a shock wave that compresses the medium through which it is transmitted.
Wavelength the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Frequency the rate at which something occurs or is repeated over a particular period of time or in a given sample.
Law of Reflection The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.
diffraction the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
rarefaction A decrease in density and pressure in a medium, such as air, caused by the passage of a sound wave
Mechanical Waves Need Matter.
Electromagnetic Wave No matter is needed.
Suns Radiation
Water Wave Are surface waves, a mixture of longitudinal and transverse wave.
Seismic Wave an elastic wave in the earth produced by an earthquake or other means.
Nuclear Reactions A change in the identity or characteristics of an atomic nucleus that results when it is bombarded with an energetic particle, as in fission, fusion, or radioactive decay.
Energy Transfer Is the transfer of energy from one object or material to another.
Matter/Medium a radio wave with a wavelength between 100 and 1000 meters.
Vibration An oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
Energy The strength and vitality required for sustained physical or mental activity.
sound Wave a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Transparent allowing light to pass through so that objects behind can be distinctly seen.
Translucent allowing light, but not detailed images, to pass through; semitransparent.
Opaque not able to be seen through
Reflect throw back without absorbing it.
Absorb take in or soak up
Transmit cause (something) to pass on from one place or person to another.

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.
