Waves on a String in an openended pipe and in a closedended pipe Warmup assume the string is fixed at both ends 1 st HarmonicFundamental Frequency 2 nd Harmonic 1 st Overtone. Section 8.5. Key Terms. Audible Sound Waves. Infrasonic Wave. Ultrasonic Wave. Echo. Mach Number (. M. ). Pressure (. p. ). Sound Intensity. Decibel (dB). Categories of Sound Waves. Sound waves fall into three categories covering different ranges of frequencies.. Section 9.2. Key Terms. Media Boundary. Free-end Reflection. Fixed-end Reflection. Transmission. Standing Wave. Node. Antinode. Fundamental Frequency/First Harmonic. Harmonics. Overtone. Media Boundaries. By the end of the day today, IWBAT…. Analyze characteristics of waves (velocity, frequency, amplitude, wavelength. ).. Do Now:. . Which of the following would be the. best physical demonstration of . 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.. More Properties of Sound. Resonance. Definition: when a force is applied to an object in repeated motion at exactly the natural frequency, an increase in amplitude occurs.. Important points: force applied AT the natural frequency!. 13.1 – Sound Waves. Objectives. * Explain how sound waves are produced. * Relate frequency to pitch. * Compare the speed of sound in various media. * Relate plane waves to spherical waves. * Recognize the Doppler effect, and determine the direction. 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 . Use your knowledge of waves & physics to answer the question.. Sound. Longitudinal wave phenomenon that consists of successive compressions and rarefactions of the medium through which the wave travels. . 1-d and 2-d waves. Wavefront. :. The actual 2-d wave . that we see moving. Ray:. The “vector”, drawn perpendicular to the . wavefront. , that shows the direction in which the wave is propagating (.
