Winding Up With Waves

Physics D and F reviewed for their Vibrations and Waves exam in class today. With yesterday being lost to snow, we picked up from Tuesday's discussion of wave interference and reflection and reviewed the chapter material in preparation for tomorrow's exam. Since we did not cover standing waves on Tuesday, that won't be on tomorrow's exam, but we will discuss standing waves in the next chapter, Sound, so we will have the material on that exam, instead. Physics D will begin with that particular new chapter in class tomorrow with a lab that will fall during the second half of the period (long block).

Honors Physics worked on a lab investigation concerning sound. We looked at sounds produced by human voices, pure tones produced by tuning forks, tones produced by a touch-tone phone and how those tones varied due to the presence of overtones or harmonics. A second investigation focused on the mathematics of music, and the mathematical relationships between notes on a scale. Tomorrow is your Vibrations and Weaves exam and Monday begins our formal discussion of sound.

Intro Physics took their Work and Energy exam today and begin a new unit - Heat and Temperature - tomorrow in class. We'll look at heat energy, temperature, specific heat, methods of heat transfer, phase change and latent heat as we move through the unit.
