1) a seaside beach in a storm Starter 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 3 1 2 11/7

Copy the diagram on p. C36 into your notes 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.

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

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 11/8

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

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

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 11/9

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

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