Waves Review

review of waves

QuestionAnswer
bottom of transverse wave trough
top of transverse wave crest
line going through middle of transverse wave rest position
waves where particles move perpendicular transverse
waves where particles move circular (perpendicular and parallel) surface
waves where particles move parallel longitudinal
most dense areas of longitudinal waves compessions
less dense areas of longitudinal waves rarefactions
crest to crest or trough to trough on transverse waves wavelength
crest (or trough) to rest position on transverse waves amplitude
# of waves completed in a given unit of time frequency
time it takes for 1 wave cycle period
SI unit for frequency Hertz
SI unit for period seconds
the horizontal line going through middle of a transverse wave rest position
waves that do NOT require a medium to pass through electromagnetic (EM) waves
waves that DO require a medium to pass through mechanical waves
apparent change in sound frequency due to the sound source or observer moving Doppler Effect
343 m/s speed of sound
3 x 10^8 m/s speed of light
states that when 2 waves are overlapping the resulting disturbance is the sum of the 2 Law of Superposition
2 waves in the same place & resulting wave is bigger than the originals constructive interference
2 waves in the same place & resulting wave is smaller than the larger original wave [may cancel out] destructive interference
wave hits a surface and bounces back reflecting
when wave bends by passing through an opening or edge of the surface diffraction
when wave bends due to passing from one medium to another refraction
states that the angle of incidence = angle of reflection Law of Reflection
combination of two waves moving in opposite directions with equal amplitude & frequency standing wave
points in a standing wave where amplitude is zero node
points in a standing wave with max amplitude antinode

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.
