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. Students . will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . Comparing Wave Properties & Energy. Essential Standard. 6.P.1Understand the properties of waves and the wavelike property of energy in earthquakes, light and sound waves.. Clarifying Objective. 6.P .. the Electromagnetic Spectrum. Waves. All waves carry … ENERGY!!!. Electromagnetic Waves (light) . Light waves are . transverse. waves. Electromagnetic. Radiation. Energy emitted from the . S8P4. . Students will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . Have your science notebook out ready to take notes. Grab the sheet from the front. Brainstorm everything you currently know about sound. Be ready to share. . Sound Vibration. Is a wave that vibrates particles of matter. Students will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . 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.. An old riddle ….. If a tree falls in a forest, and no one hears it, does the tree make a sound?. What is “sound”?. Sound Waves. To a scientist, a tree makes a sound whether someone hears it or not.. Wave Properties. There are 6 main properties, or interactions, of waves that occur when a wave comes in contact with another wave , or a boundary. . The 6 Interactions of waves are. Interference. Diffraction. - . 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. . vibrations. - repetitive back and forth motions. Waves – a traveling . disturbance . that carries . energy . from one location to another. . Think about waves like . ripples . in a pond. . Mechanical Waves. Wave. particles vibrate parallel to the direction of the motion of the wave. Terminology. Compressions. : areas where particles come closer together. Rarefactions: . regions where particles are further apart. Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review. Mechanical Wave overview. Transverse Waves. Surface Waves. Longitudinal Waves (general). Sound Waves (Longitudinal).
