The Sun!

How nice to have a little sunshine today after the yuck of the weekend and week...

Physics A discussed physical descriptors of vibrations, such as amplitude, frequency and period. The formulas for calculating the period of a mass-spring and pendulum system were reviewed and tied into our recent lab unit. Physics B reviewed the last of those labs in class today and then began to examine the waves that vibrations were responsible for producing. We put a basic definition to waves, contrasted mechanical/electromagnetic and transverse/longitudinal waves and added a few additional descriptors such as wavelength and wave speed. Tomorrow, we take a look at wave interactions, while A Block takes on this material instead.

Intro Physics and Honors Physics reviewed for tomorrow's exams. We walked through the material and addressed any last-minute concerns about the topics. On Monday, Intro Physics starts waves and Honors Physics takes on light, color and reflection.
