Behaviors of Light and Sound Waves

Reflection of Light Give an example of reflection of light. You can write words or draw a picture. Reflection of Sound Give an example of reflection of sound. You can write words or draw a picture. Write the Law of Reflection below the diagram. How CDs and DVDs Work What behavior of light is used to read CDs and DVDs? Absorption Diffraction Refraction Reflection Formation of Rainbows What behavior of light is responsible for the creation of rainbows? Absorption Diffraction Refraction Reflection Why does the straw look bent? Absorption Diffraction Refraction Reflection Diffraction - the bending of a wave to move around an obstacle or through an opening. Diffraction Use the slit animations to investigate how waves are diffracted. Diffraction of Light Diffraction of Sound What behavior of sound allows you to hear around corners? reflection refraction diffraction absorption Transmission of light means that the light goes through an object. In order for the light waves to pass through an object, the object must be_. Trans-parent Translucent Opaque Light reflects off of objects that are _, allowing us to see them. Trans-parent Translucent Opaque White light consists of red, orange, yellow, green, blue, indigo, and violet. Which color(s) of light are being reflected by the green leaf? Red and blue Green Red, orange, yellow, blue, indigo, and violet Green and yellow White light consists of red, orange, yellow, green, blue, indigo, and violet. Which color(s) of light are being absorbed by the green leaf? Red and blue Green Red, orange, yellow, blue, indigo, and violet Green and yellow Which colors are being reflected by the black part of the umbrella? White Black All the colors None of the colors Sound will travel fastest through solids because they are more dense than liquids and gases. Sound travel slowest through gas because the density of gas is less than that of solids or liquids. Concave and Convex Lenses Drag the words and pictures to the correct box.
