Waves

TermDefinition
Compressional Wave Mechine made that causes particles in matter to move back and forth along the direction the wave travels
Diffraction Bending of waves around an object
Electromagnetic Spectrum Complete range of electromagnetic wave frequencies and wavelength
Electromagnetic Wave Waves that can travel through matter or empty space includes radio waves infrared wave X rays and gamma rays
Frequency Number of wavelengths that pass a given point in one second measured in hertz
Infrared Waves Electromagnetic waves with wavelengths between about one thousandth of meter and 700 billionths of a meter
Intensity Amount of energy a wave carries past a certain area each second
Law of Reflection States that the angel the incoming wave makes with the normal to the reflecting surface equals the angle the reflected wave makes with the surface
Pitch Humans perception of the frequency of sound
Refraction Change in direction of a wave when it changes speed as it travels from one material into another
Reverberation Repeated echoes of sound waves
Transverse wave a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane
Ultraviolet Wave light is electromagnetic radiation with a wavelength from 400 nm to 10 nm, shorter than that of visible light but longer than X-rays.
Wave a long body of water curling into an arched form and breaking on the shore.
Wavelength the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

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.
