Still Wavin'

We are still working with waves, with Physics A and B concentrating on sound, Intro Physics getting the basics of vibrations and waves and Honors Physics working through light and reflection.

Physics A and B took their vibrations and waves exams yesterday, after a bit of lab work on wave properties and some review time. Tomorrow, we start in on sound!

Intro Physics discussed further characteristics of waves such as wave speed and looked at factors that affect the speed of both electromagnetic and mechanical waves. Be very sure you are aware how density of the medium impacts the speed of both EM and mechanical waves and that you can use the wave speed formula (and distance/time) to calculate the speed of a wave. Tomorrow, we start on wave interactions.

Honors Physics leaped from work with mirrors to color and polarization. We contrasted the additive and subtractive color systems, defined polarization and looked at methods of producing polarized light. Our little activity with the polarizing filters will be familiar when we do Monday's lab work with light intensity and polarization. Tomorrow's lab work centers around spherical mirrors and image formation.
