Question

which type of waves can be used to clear a blockage from small tubes in the kidneys? sound waves and visible light x - rays and radio waves radio waves and sound waves visible light and x - rays

Explanation:

In medicine, shock - wave lithotripsy uses sound waves to break up kidney stones (blockages in kidney tubes). X - rays are used for imaging, not for breaking up blockages directly. Radio waves and visible light are not used for this purpose.

Answer:

None of the above options are correct. Sound waves (specifically shock - waves in lithotripsy) are used to clear blockages in kidney tubes, but the given options combine them with inappropriate wave types.
