This document provides a summary of the day's schedule and lessons on light waves. It discusses monochromatic and polychromatic light. The key evidence that light behaves as a wave is discussed, including that it has a wavelength, frequency, reflects, refracts, diffracts, and exhibits interference. Polarization of light is then explained, including how polarized filters block one orientation of waves. Homework involves a pre-quiz on light waves, with a focus on reflection and refraction questions.
