a. Identify the characteristics of electromagnetic and mechanical waves.
b. Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption).
c. Explain how the human eye sees objects and colors in terms of wavelengths.
d. Describe how the behavior of waves is affected by medium (such as air, water, solids).
e. Relate the properties of sound to everyday experiences.
f. Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

When a wave enters a new medium at an angle, one side of the wave changes speed before the other side, causing the wave to bend.
• amount of bending depends on the speed of light in both materials
• the greater the difference between the speeds of light in the two media, the more the light is bent
