Transcript of "Wavy gravy basics"

  1. 1. WavyGravy
  2. 2. A wave is a traveling disturbance that carries energy from one place to another
  3. 3. Basically waves are made by something moving:• Sound: Something vibrates and passes the vibration on.• Light: An electron jumps from one shell to another (rapidly!)• Ocean: The wind moves the water, (or anything else you can think of)
  4. 4. Waves can either travel through:• Nothing (space, vacuum) ….Light can do this• or Something: (solids, liquids, gases) … – Whatever the wave travels through is known as the medium
  5. 5. WAVES wavelength crest amplituderestingposition trough How often a crest hits you per second is the wave’s frequency
  6. 6. Units of measure:• Amplitude (A) and wavelength (λ) are distances. Measure in cm, m, etc.• Frequency (f) is # of waves/second.• Frequency is measured in Hertz (ouch)
  7. 7. Transverse waves• “snakey” waves• these are the types of waves most people think of• “perfect” water waves are transverse• The disturbance is at a right angle to the wave’s direction of travel
  8. 8. Longitudinal Waves• “squeeze” waves• “compressional” waves• The compressions of the medium get passed along• Example: sound (think of a speaker that is “pumping”)
  9. 9. Slinky: Do these and show teacher the outcomes and take notes• Make a transverse wave.• Make a longitudinal wave• Using a transverse wave do these: – How do you make the wave have bigger amplitude? - How do you make the wave have a different wavelength? -How do you get the wave to travel slower or faster?
  10. 10. Combined Waves• Things usually don’t fit in perfect categories• Many waves are a combination of transverse and longitudinal
  11. 11. Terms to know• Wave:• Vibration: • Reflection:• Medium: • Refraction:• Longitudinal • Diffraction: Wave: • Interference:• Transverse Wave: • Standing Wave:• Frequency: • Hertz (Hz)
