X-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.
Which one of the following waves does not belong to the category of the other three ?
