Answer:

Electronic waves:

radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

Mechanical waves:

Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

Explanation:

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
