Draw a wave showing the AMPLITUDE?

Cards in this deck (26)

  1. 1What is a wave?A wave is an OSCILLATION or VIBRATION that transfers energy or information
  2. 2What else can a wave be?An undulation on the surface of water
  3. 3Name two uses of waves?A microwave to cook food and sound waves to communicate
  4. 4How many important features do waves have?3
  5. 5One important feature of a wave is the AMPLITUDE. What is the AMPLITUDE of a wave?The distance from the middle to the top or bottom of a wave
  6. 6Draw a wave showing the AMPLITUDE?Draw a wave showing the AMPLITUDE?
  7. 7One important feature of a wave is the FREQUENCY. What is the FREQUENCY of a wave?The number of waves that go past a particular point per second
  8. 8One important feature of a wave is the WAVELENGTH. What is the WAVELENGTH of a wave?The distance from one point on a wave to the same point on the next wave
  9. 9Draw a wave showing the WAVELENGTH?Draw a wave showing the WAVELENGTH?
  10. 10What is the top of a wave called?The PEAK or CREST
  11. 11Draw a diagram showing the PEAK or CREST of a waveDraw a diagram showing the PEAK or CREST of a wave
  12. 12What is the bottom of a wave called?The TROUGH
  13. 13Draw a diagram showing the TROUGH of a wave?Draw a diagram showing the TROUGH of a wave?
  14. 14If you sent pulses down a slinky spring by moving your hand at right angles to it, what type of wave would this produce?A TRANSVERSE wave on the slinky
  15. 15In a transverse wave, how does the oscillation (energy transfer) pulse?At 90 degrees (right angle) to the direction of the wave
  16. 16If you sent pulses down a slinky spring by pushing and pulling the slinky, what type of wave does this produce?A LONGITUDINAL wave.
    It is in the same direction as the spring itself
  17. 17In a LONGITUDINAL wave, how does the oscillation (energy transfer) pulse?Parallel to the direction of the wave
  18. 18What is it called when the coils of the spring are close together?A COMPRESSION
  19. 19What is it called when the coils of the spring are further apart?A RAREFACTION
  20. 20What type of wave is a sound wave?LONGITUDINAL
  21. 21What type of wave is a light wave?TRANSVERSE
  22. 22What is it called when a wave bounces off of a surface or barrier, just like a football bounces off of a wall?REFLECTION
  23. 23What is the wave coming into the barrier called?The INCIDENT wave
  24. 24What is the wave bouncing off the barrier called?The REFLECTED wave
  25. 25Draw a diagram and label a wave bouncing off of a barrier?Draw a diagram and label a wave bouncing off of a barrier?
  26. 26What is it called when waves are put together and therefore add up or cancel out?They SUPERPOSE
