Which term describes converting electrical energy into acoustic energy in the transducer?

• A. Reflection
• B. Refraction
• C. Absorption
• D. Conversion

Answer: (D)

In the transducer, the electrical pulses from the ultrasound system are converted into mechanical vibrations, producing acoustic energy that travels into the body. This energy-form change is what "conversion" describes—the transducer transforms electrical energy into sound energy. The other terms relate to what happens to sound after it’s emitted: reflection is sound bouncing off interfaces, refraction is bending of sound as it changes speed at boundaries, and absorption is energy lost as heat within the tissue. So the process inside the transducer that makes the sound is conversion.
