Moving On To Light

Physics D, F and Honors Physics began their discussion of light today with an overview of the nature of light as a transverse, electromagnetic wave (when it behaves as a wave), the members of the EM spectrum and their uses, the speed of light and how Huygens viewed light waves and their propagation. Physics D and Honors Physics also looked at light intensity, but Physics F will get there on Monday, when they will also start, with the other sections, on an examination of reflection and reflection by flat mirrors.

Intro Physics discussed yesterday's lab investigation on phases and phase change before turning attention towards the liquid and gas phases of matter. We continued to describe matter in terms of energy, particle motion, volume and shape and saw how the pattern of increasing energy took solids to liquids and then gases. We'll hit plasma on Monday and then begin our look at phase changes, phase change diagrams and latent heat.
