Mon-Day 1
Physics - took part I of the Waves exam.
We introduced the second part of our unit on waves, which focuses mainly on the phenomena of diffraction and refraction of EMR/light waves.
We came up with a definition of diffraction based on what it looks like, a wave's spreading out/bending around a barrier.
We also observed that, the narrower an opening is relative to a given wavelength, the greater the degree of diffraction.

AP Chem - we finished the example of adding a strong base to a buffer; an additional example, using a basic buffer will be given out to you in the notes; the process is identical in determining the effect on the pH.
We then started our next subtopic, that of choosing the right conjugates and quantities to make a buffer of a particular pH.
There WILL be a descriptive chem quiz tomorrow involving 3 or 4 of the following reaction types (you must know the specific type also):
double replacement, single replacement, gas-forming, metal-ligand, active metal in water, metal oxide in water, non-metal oxide in water, redox using a strong oxidizer, and select organic reactions: substitution, addition, esterification, combustion.
