reflector spacing and propagation speed - Answer>>> reflector spacing and propagation speed
Which of the following best describes the features of a sound wave and medium that determine the speed of sound in the medium?
density of the medium and stiffness of the medium
density of the medium and power of the sound beam
elasticity of the medium and frequency of the sound beam
stiffness of the medium and elasticity of the medium

low intensity and low frequency - Answer>>> low frequency and low signal amplitude
While propagating, a sound wave is refracted. Finally, it returns to the transducer. The system processes the sound wave as if it has:
refracted and returned
traveled in a straight line, reflected and returned
traveled in a straight line, attenuated, reflected & returned - Answer>>> traveled in a straight line, reflected and returned
