PPT-Unit 4: Waves, Sound, and Color

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. Chapter 16. 16.1 The Nature of Waves. A Wave:. Traveling disturbance. Carries energy from place to place. Two Different Types:. Transverse. Longitudinal . Slinky. If the end is jerked up and down, an upward pulse is sent traveling toward the right.. What is a wave?. A wave is a repeating disturbance or movement that transfers energy through matter or space. Waves transfer energy not matter. The water waves below are carrying energy but are not moving. Waves can only exist as they have energy to carry.. the Electromagnetic Spectrum. Waves. All waves carry … ENERGY!!!. Electromagnetic Waves (light) . Light waves are . transverse. waves. Electromagnetic. Radiation. Energy emitted from the . waves_04. 1. flute. clarinet. click for sounds. waves_04: MINDMAP SUMMARY - SOUND WAVES. 2. Sound waves, ultrasound, compressional (longitudinal) waves, pressure, particle displacement, medical imaging, superposition principle, stadning waves in air columns, constructive interference, destructive interference, boundary conditions, pipe – open and closed ends, nodes, antinodes, speed of sound in air, period, frequency, wavelength, propagation constant (wave number), angular frequency, normal modes of vibrations, natural frequencies of vibration, fundamental, harmonics, overtones, harmonic series, frequency spectrum, radian, phase, sinusoidal functions, wind musical instruments, beats, beat frequency, Doppler Effect, Doppler radar, shock waves. 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 . 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. © 2016 Pearson Education, Inc.. Goals for Chapter 12. To describe mechanical waves.. To study superposition, standing waves and sound.. To present sound as a standing longitudinal wave.. To see that waves will interfere (add constructively and destructively).. 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.. Medium. The material through which a wave travels.. Ex: Gas (air), liquids (water), and solids (Rope) can all be mediums.. https://www.youtube.com/watch?v=w2s2fZr8sqQ. Pitch. The pitch of a sound is determined by the rate of vibration, or frequency, of the sound wave.. 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. Remain as quiet as you can for 1 minute.. I will tell you when to begin, and when to stop.. In the margin of your paper, write down all of the different sounds that you hear in the environment around you.. Sound Chapter 12 Sound hunt Remain as quiet as you can for 1 minute. I will tell you when to begin, and when to stop. In the margin of your paper, write down all of the different sounds that you hear in the environment around you. 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.. water. waves.... 4/5/2019. Physics 214 Fall 2010. 2. 1S-13 Slinky on Stand. Creating longitudinal compression waves in a slinky. What happens when you pull back and release one end of the slinky . ? .
