W1 W1 Presentation Transcript

  • WAVES: DAY 1 9-9-2013
  • Think – Pair - Share What is a wave?
  • When most people hear the word “wave” they immediately think of waves in the ocean… So lets begin learning about waves by observing this type of wave in action.
  • WATCH “CODE RED” ON YOUTUBE
  • What is a Wave?  Scientists define a wave as….  A repeating disturbance (vibration) that moves through a medium carrying energy from one location to another.  Medium: a substance or material that carries the wave. A Wave Transports Energy and Not Matter
  • Journal Entry: Is “The Wave” really a wave? Explain. WATCH STADIUM WAVE AT KINNICK STADIUM ON YOUTUBE
  • Waves: Day 2 (9-10-2013) Watch Bill Nye on Youtube
  • Waves: Day 3 9-11-2013
  • Warm Up Stand up paddle boards (SUP’s) were first used by pacific islanders to travel between nearby islands. Why bother with paddling? Why not just surf waves the whole way across like a rad surfer dude?
  • Defining Waves  Wave: A repeating disturbance (vibration) that moves through a medium carrying energy from one location to another.  Medium: a substance or material that carries the wave. A Wave Transports Energy and Not Matter
  • Quick Quiz: Would this be a wave?  Is there an initial disturbance, or energy input?  Is energy transported from one point to another?  Is there a transport medium?  Is the energy transported through the medium, with the medium itself returning to it’s original position? NOT A WAVE
  • Quick Quiz: Would this be a wave?  Is there an initial disturbance, or energy input?  Is energy transported from one point to another?  Is there a transport medium?  Is the energy transported through the medium, with the medium itself returning to it’s original position? WAVE

  • The Great Debate Isaac Newton: Light energy is carried as a packet of energy. Christiaan Huygens: Light energy is carried as a wave. Then along came Thomas Young
  • “Young’s Double Slit Experiment” on Youtube
  • Technically your both right…
  • So what is the medium for light? The Universes Electromagnetic Field!
