Waves

TermDefinition
Wave A disturbance that moves through matter or space.
Transverse Wave Cause particles in matter to move back and forth at right angles to the direction in which the wave travels.
Compressional Wave Causes particles in matter to move back and forth along the same direction in which the wave travels.
Wavelength The distance between one point on a wave and the nearest point moving with the same speed and direction is the wavelength
Frequency The number of wavelengths that pass by a point each second
Law of Reflection The angle that the incoming wave makes with the normal equals the angle that the out going wave makes with the normal.
Refraction the change in direction of the wave when it changes speed as it travels from one material to another.
Diffraction Bending of waves around an object.
Opaque Materials allow no light through
Translucent Allows some light through
Transparent Materials allow nearly all light to pass through
Reflect A light hitting an object and bouncing off of it
Absorb Soak up light
Transmit Let's light through object
Loudness As the amplitude energy increases the sound gets louder
Pitch As the energy decreases softer
Echo Location To navigate
Echo A reflected sound wave
Doppler Effect The change in frequency that occurs when a source of sound is moving relative to a listener.
Electromagnetic spectrum Complete range of electromagnetic wave frequencies and wavelengths
Electromagnetic Wave Waves that can travel through matter or empty space,Includes radio waves visible light waves
Infrared Wave Electromagnetic waves with wave lengths
Reverberation repeated echos of sound 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.
