Vacuum
Correct, electromagnetic waves can travel through a vacuum. Sunlight is an example of this.
As sound is a mechanical wave (unlike light, an electromagnetic wave), it requires a medium in which to travel, therefore, it cannot travel through a vacuum.
Mechanical waves may travel through any medium except vacuum.
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.

Shear waves travel through solids. They cannot travel through liquids and gasses (unlike compressive waves) and they can't travel through a vacuum (unlike electromagnetic waves).
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
Mechanical waves require media through which they can travel.
Mechanical waves require media through which they can travel.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
A mechanical wave can travel through a medium with mass and elasticity. Examples are air and water (sound waves), earth (earthquakes).
