QuestionAnswer
Wave a periodic disturbance in a solid, liquid, or a gas as energy is transmitted a medium
medium a physical environment in which phenomena occurs
Mechanical Wave a wave that requires a medium through whih travels
Electromagnetic wave a wave that consists of oscillating electric and magnetic fields which radiate outward at the speed of light
transverse wave a wave in which the particles of the medium more perpendicular to the direction the wave is traveling
longitudinal wave a qave in which the particles of the medium vibrate parallel to the direction wave motion
Crest the highest point of the wave
trough the lowest point of the wave
amplitude the maximum distance that the particles of a waves medium vibrate from the rest position
wave length the distance from any point on a wave to an identicle point on the next wave
period the tie that it takes a complete cycle or wave oscillation to occur
frequency the number of cycles or vibration per unit of time
dropper effect an observed change in the frequency of a wave when the source or observer is moving
reflection the bouncing back of a ray of light, sounds, or heat when the ray hits the surface
difflaction a change in the direction of a wabe when the wave finds an obsticle or an edgesuch as an opening
refraction the bending of waves when they pass from one medium into another
interference the combination of twoor more waves of the same frequency that results in a single wave
constructibe interference wavaes combine so that the resulting wave is bigger
destructive interference waves combine so that the resulting wave is smaller than the largest
standing wave a pattern of vibration that stimulates a wave that is standing still

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.
