  1. In each situation below, what might happen to show that the waves transfer energy? 1) a seaside beach in a storm 2) an earthquake 3) movement of coils Starter 3 1 2

  2. Copy the diagram on p. C36 into your notes. Also copy the definition of the following word into your notes: • sound- a wave that is produced by vibrating object and travels through matter.

  3. Read pps. C37-C43. On p. C43 do questions 1-6.

  4. Starter • Starter: Decide if these statements are true. If not, correct them. • 1) In a longitudinal wave, the vibrations move perpendicular to the direction of the wave. • 2) Sound is a type of electromagnetic wave. • 3) Vibrations pass through many parts of the eardrum. p. C14 p. C37 p. C39

  5. Copy the following definitions into your notes: • pitch-the quality of highness or lowness of a sound • hertz-the unit for measuring frequency and also pitch • ultrasound-sound waves in the range above 20,000 hertz • resonance-the strengthening of a sound wave when it combines with an object's natural vibration

  6. Read pps. C45-C51. On p. C51 do questions 1-6

  7. Starter For the Starter do not write the definitions, number them 1-3 and then put the letter of the term that matches that definition. • Starter: Match each of the definitions in the first column to one of the terms in the second column • Definitions Terms • sound waves with frequency greater than 20,000 hertz a) pitch • the measure of the height of a wave's crest b) ultrasound • how high or low a sound is c) amplitude

  8. Copy the following definitions into your notes: • intensity-the amount of energy of a wave, per wavelength • decibel-unit used to measure sound • amplification-the increasing of the strength of an electric signal • acoustics-the scientific study of sound

  9. Read pps. C52-C56. On pC56 do questions 1-6.

  10. Starter • You own a movie theater. Explain how you could control the loudness of the sound of movies. How would you eliminate as much audience noise as possible? *Element Baby Book due today*

  11. Copy the following definitions into your notes: • echolocation-sending out ultrasound waves and interpreting the returning sound echoes • sonar- instruments that use echolocation to locate objects

  12. Read pps. C58-C63. On p. C63 do questions 1-6.
