PPT-Sound COS: #18 Use Models to determine how light and sound waves differ in how they are

Producing and Detecting sound What is sound The sound you hear is sound waves that can only travel through matter Sound waves are longitudinal waves Sources of sound Every sound comes from a vibration which is the energy that the wave uses to carry the sound.

Remember: the color of an object that you see is the color it is reflecting; the object absorbs all other colors.. A lime. Colors Reflected:. Colors Absorbed: . Red orange yellow green blue indigo violet. Sound. Sound waves are compressional waves.. Two regions: compressions and rarefactions. Sound travels faster in liquids and solids than in gases.. Why? The molecules in liquids and solids are closer together.. Sound waves are made up of a series of regions of high and . low pressure. . The areas of high pressure are called . compressions. . The . areas . of low pressure are called . rarefactions.. Wave energy travels through the material. But a particular piece . - . Recognize that light waves, sound waves, and other waves move at different speeds in different materials.. . ALSO ASSESSES: SC.7.P.10.2 . Observe and explain that light can be reflected, refracted, and/or absorbed. . Nature of science:. Imagination: It is speculated that polarization had been utilized by the Vikings through their use of Iceland Spar over 1300 years ago for navigation (prior to the introduction of the magnetic compass). Scientists across Europe in the 17th–19th centuries continued to contribute to wave theory by building on the theories and models proposed as our understanding developed.. Light. Light.

When light encounters a different medium it can either be reflected, absorbed, or pass through. Most of the time it is some level of each.. A blue shirt reflects blue light (and a few others) absorbs all other colors of light and allows small intensities of all colors (white light) to pass through. .
