ultrasound physics What wave property is changed by an increase in intensity? Wavelength Frequency Acoustic velocity Acoustic pressure

A pulse in a less dense medium is traveling towards the boundary with a more dense medium. Mediun 1 Medium2 Less Dense More Dense The amplitude of the transmitted wave will be . the incident wave. a. greater than O b. less than c. same as When two objects are at the same temperature, then . a. the molecules stops moving O b. they have the same number of molecules O c. there is no heat transfer between them o d. it cools

Is the speed of sound independent of frequency? Explain.

Transverse waves traveling along a string have the following properties. Amplitude of the wave = : 2.40 mm Wavelength of the wave = 0.150 m Speed of the wave = 348 m/s Determine the time for a particle of the string to move through a total distance of 1.50 km. 4.0 67.3 S If the string is held under a tension of 1022 N, determine its linear density 4.0 118497 X g/m

A dolphin in seawater at a temperature of 25°C emits a sound wave directed toward the ocean floor 138 m below. How much time passes before it hears an echo? (The speed of sound in ocean water is 1533 m/s.) Additional Materials O eBook Stephen Frink/Pho tographer's Choice/Getty Images
