Reflection

The law of reflection is introduced as we learn about the difference between specular and diffuse reflection and discover the difference between real and virtual images.

Vocabulary

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.

Georgia Standards of Excellence

SP4
Obtain, evaluate, and communicate information about the properties and applications of waves.
d
Plan and carry out investigations to characterize the properties and behavior of electromagnetic waves. (Clarification statement: Properties of waves include, but not limited to, amplitude, frequency, wavelength, and the relationship between frequency or wavelength and the energy of the wave.)
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.
