Mechanical vs Electromagnetic

What is the main difference between Electromagnetic (EM) waves and Mechanical waves?

• They are the same thing just has different names

• EM waves can transfer energy without a medium, while mechanical waves needs a medium to transfer energy.

Radio waves, microwaves, X-Rays, and gamma rays are considered which type of wave?

• Mechanical Wave

• Electromagnetic (EM) waves
