\nThe correct answer is Sound waves.
\n<\/section>\n
\nX-rays, microwaves, and radio waves are all forms of electromagnetic waves. They are part of the electromagnetic spectrum, travel at the speed of light in a vacuum, and do not require a medium for propagation. Sound waves, on the other hand, are mechanical waves. They are vibrations that travel through a medium (like air, water, or solids) and require a medium to propagate.
\n<\/section>\n
\nElectromagnetic waves are transverse waves caused by oscillations of electric and magnetic fields. Mechanical waves like sound waves can be longitudinal or transverse and are caused by the vibration of particles in a medium. This fundamental difference in nature and propagation makes sound waves distinct from the other three types of waves listed.
