1. Now we will study Sound in detail!
Recall that Simple Harmonic Motion is at the root of waves
We will revisit waves in general
(including traveling waves and standing waves)
Longitudinal
Transverse
Waves on a taut string
Light (chapter 24)
Now we will study Sound in detail!

2. WAVES: All that we learned about waves for transverse waves on strings, we will still use and also apply to sound waves in air
Traveling waves
Note features such as amplitude, wavelength, frequency
Relate speed to wavelength and frequency
Calculate the specific speed of a transverse wave on a taut string
Calculate the speed of sound waves in air
Standing waves
Know how a standing wave is produced
Know different standing wave patterns for guitar strings and organ pipes (and be able to make calculations related to wavelength and frequency)

3. WE WILL STUDY THE FOLLOWING WAVE PHENOMENA (as they apply to sound waves)
Beats
Periodic variation in loudness from waves of slightly different frequency
Doppler Effect
Shift in frequency of a wave from motion of the source or receiver of waves
