Wave Types and Characteristics
Ninth graders identify the different parts of a wave. In this physics lesson, 9th graders observe wave behavior as it travels through a boundary. They determine the relationship between wavelength, frequency and velocity.
Cornell University
Light Waves: Grades 6-8
Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.
