Which of the following is among the five parameters initially determined by the sound source?

Explanation:
Frequency is the parameter set at emission by the sound source. The transducer fixes how many cycles per second the wave has, which is what frequency measures. Wavelength, while related, also depends on how fast sound travels in the medium, so it’s not determined by the source alone. Attenuation and scatter describe how the wave weakens and redirects as it passes through tissue, and these effects depend on tissue properties and distance rather than the source’s settings. So frequency is the correct choice because it is the parameter determined by the sound source right at emission.
