Physics Edelman's Review (100% verified)

sound waves are correct answers mechanical & longitudinal acoustic variables correct answers pressure, density, distance acoustic parameters correct answers period, frequency, amplitude, power, intensity wavelength, propagation speed when the frequency of the wave differs, what kind of interference? correct answers constructive & destructive two waves are traveling and arrive at a location at the same time, what event takes place? correct answers interference period correct answers time from the start of one cycle to the start of the next cycle period is determined by correct answers sound source frequency correct answers number of cycles that occur in one second hertz is another way to say correct answers per second frequency determined by correct answers sound source ultrasound correct answers higher than 20,000 Hz (20 kHz) period and frequency relationship correct answers inversely related period and frequency are correct answers reciprocals used to describe the magnitude of a wave correct answers amplitude, power, intensity power is proportional to correct answers amplitude squared intensity = correct answers power/area intensity is proportional to correct answers power wavelength determined by correct answers sound source and medium wavelength and frequency relationship correct answers inversely related wavelength = correct answers 1.54/frequency speed of sound in soft tissue correct answers 1540 m/s
