In this direct instruction lesson, students draw sketches in their science notebooks in order to make sense of wave properties. Resources include a slideshow presentation on the properties of waves and multiple examples of student work.
Students will use a variety of objects to participate in a partner activity and communicate using light and sound waves. Resources include a video, pictures and videos of the lesson in action, and examples of student work.
At this univeristy physics department site, the polarization of light is explained and illustrated. Methods for analyzing light to determine the degree of polarization are stated and explained with equations.
Video provides a basic introduction to the phenomenon of light, the electromagnetic radiation spectrum, wave and particle-like behavior, and how to calculate the wavelength or frequency of a light wave. [9:36]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
At this college physics department site, the polarization of light is explained and illustrated as well as the primary methods of polarization (scattering, reflection, and refraction).
The behavior of light waves is introduced and discussed. Also, polarization, color, diffraction, and interference are introduced and discussed thoroughly as supporting evidence of the wave nature of light.
The operation of Polaroid filters on a pair of sunglasses is shown.
Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

By the end of this section, you will be able to:
Describe important physical features of wave forms
Show how physical properties of light waves are associated with perceptual experience
Show how physical properties of sound waves are associated with perceptual experience
Physicists and astronomers have different views of photons, what they are, and how they behave. Watch as three University of Nottingham scientists discuss the nature of photons and why the study of light is important. [8:32]
