which type of sound wave - object interaction breaks down kidney stones and destroys cancer…

Answer:

No option is correct. The correct answer is high - intensity focused ultrasound (HIFU) which is a form of sound - wave interaction that uses high - intensity sound waves to break down kidney stones and destroy cancer cells. But if we have to choose from the given options, none of them are responsible for this function. Absorption is the transfer of energy from the sound wave to the object, diffraction is the bending of sound waves around obstacles, reflection is the bouncing back of sound waves from a surface, and refraction is the change in direction of sound waves as they pass from one medium to another.

Brief Explanations:

The listed options do not describe the sound - wave interaction for breaking kidney stones and destroying cancer cells. Each option has a different physical phenomenon related to sound waves that is not relevant to this medical application.
