  1. ScienceMonday, November 4th (week 2) Day: 10hr 36min Rise-6:40 Set-?:?? Moon: waxing crescent, 1% illuminated Objectives: I will describe how waves move energy.

  2. Warm Up! Question: Draw and label the parts of a longitudinal wave.

  3. Important Information Due Today: Bellwork Week 1 Homework Tonight: Get your report card slip signed! Upcoming Events: Early Release on Friday?

  4. Transverse Waves* • Crest- highest point on a wave • Amplitude- Volume of a wave (height of a wave) • As wave height increases, volume increases • Measured in Decibels • Trough- lowest point on a wave • Frequency- Pitch, high or low (length of a wave) • As wavelength increases, pitch decreases • Measured in Hertz

  5. Amplitude versus Frequency Amplitude • Which one will have the higher volume? Frequency • Which one will have the higher pitch?

  6. What can you hear? Decibels (dB): Volume • Normal Speech: 60dB • Library: 40dB • Close Whisper: 20dB • Jet Engine: 140dB • Loud Rock Music: 110dB • Subway Train: 100dB • Busy Street Traffic: 70dB • 120dB or above usually causes pain to the ear Hertz (Hz): Pitch • Young people can hear frequencies between 20-20,000 Hz • Dogs can hear frequencies that range from 67-45,000 Hz • As you age, your ability to hear high frequency sound decreases.
