PPT-WAVES, SOUND, AND LIGHT

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 . First a little . vocab. …. WAVE: . A periodic disturbance in a solid, liquid or gas. Some waves (light) can travel through empty space. MEDIUM:. Matter or space through which waves travel. I. Waves transfer energy. 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.. 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. S8P4b. Describe how the behavior of light waves is manipulated causing reflection, refraction, diffraction, and absorption.. Reflection. Reflection occurs when a wave strikes an object or surface and bounces off.. - . 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. . Section 1. Objectives. 1. Explain the relationship among waves, energy, and matter. 2. Describe the difference between transverse waves and compressional waves. A. Waves Carry Energy. Waves (rhythmic disturbances that carry energy without carrying matter) can carry energy by itself or with matter. 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.. 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. 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..
