### Science

SP4

Obtain, evaluate, and communicate information about the properties and applications of waves.

SP4.d

Plan and carry out investigations to characterize the properties and behavior of electromagnetic waves.

SP4.e

Plan and carry out investigations to describe common features of light in terms of color, polarization, spectral composition, and wave speed in transparent media.

• Analyze experimentally and mathematically aspects of reflection and refraction of light waves and describe the results using optical ray diagrams.
• Perform calculations related to reflections from plane surfaces and focusing using thin lenses.
SPS9

Obtain, evaluate, and communicate information to explain the properties of waves.

SPS9.c

Develop models based on experimental evidence that illustrate the phenomena of reflection, refraction, interference, and diffraction.

S8P4

Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.

S8P4.d

Develop and use a model to compare and contrast how light and sound waves are reflected, refracted, absorbed, diffracted or transmitted through various materials.

-Compare and contrast specular reflection and diffuse reflection.

-Define and use the law of reflection conceptually and mathematically.

-Experiment with a plane mirror noting the location of the image formed and whether it is real or virtual.

diffuse reflection - when light rays strike a rough surface.

law of reflection - this law states that the angle of the incident ray equals the angle of the reflected ray.

reflection - when a wave bounces off a surface when interacting with a material.

specular reflection - when light is reflected off of a shiny or glossy surface.

The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators.To order your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units.
