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.
Unlike sound electromagnetic waves can travel trough empty space
Microwaves are part of the electromagnetic spectrum, and as such they do not require any physical presence to aid passage, unlike sound waves which do require a medium through which to travel.

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).
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.
Light is an example of electromagnetic radiation. EM radiation unlike other waves of energy doesn't need a medium to travel through hence why light energy can travel from the sun to the earth through the vacuum of space.

The sun is a mechanical wave because it doesn't have radio waves in it and it doesn't have spectrum energy, unlike electromagnetic energy.

Seismic waves are vibrations generated by an earthquake. They travel along the surface of the Earth and through the earth. They are a type of wave known as a mechanical wave and as such (unlike electromagnetic waves) require a medium through which to travel. Seismic waves can be split into body and surface waves. The body waves can be split into two main types, the P-wave or primary wave which is a compression or longitudinal wave which can travel through solids, liquids and gasses and the S-wave which is a transverse or shear wave and can only travel through solids.
