Examples of mechanical waves are waves in the ocean and sound waves from devices like mouths, trombones, and radios. Electromagnetic waves like sunshine and X-rays are not mechanical waves because matter is not doing the waving.

An electromagnetic wave is not a mechanical wave.
light waves are electromagnetic
True, because mechanical waves require a medium for propagation.

-- There is nothing electric or magnetic about a towel. -- It doesn't use batteries or photovoltaic cells, it doesn't attract charged objects, and when you hang it up and it's free to turn, it shows no tendency to point north. -- It doesn't glow in the dark, shock you when you touch it, or pick up radio signals. -- It doesn't generate electric current, make cross-hatch lines on the TV picture, or heat a piece of meatloaf wrapped in it. -- If you pick it up with your hand and wave it with your arm, then it waves. -- This all sounds pretty mechanical.

An electromagnetic wave is not a mechanical wave.
Electromagnetic waves
Mechanical.
Electromagnetic waves, if it was mechanical, something would literally have to make them!
light waves are electromagnetic
True, because mechanical waves require a medium for propagation.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
mechanical waves carry mechanical energy and electromagnetic waves carry electromagnetic energy.
