Which waves are electromagnetic and can travel through a vacuum?

light and heat waves
longitudinal and transverse waves
sound waves < i think
surface waves

The waves that travel through a vacuum is, light and heat waves.

Explanation :

Electromagnetic waves: These are waves which can travel through vacuum. These have electrical and magnetic component associated with them. They travel with the speed of light. They does not require a medium to travel. For Example: Infrared waves, Microwaves, light waves, heat waves.

Mechanical waves: These are the waves that require a medium to travel so that they can transport their energy from one location to another. For Example:  Sound waves, surface wave.

Surface wave : It is defined as a seismic wave that travels along or parallel to the earth's surface.

Longitudinal and transverse waves  are also require a medium to travel.

Hence, the waves that travel through a vacuum is, light and heat waves.

this process is called "phosphorylation." a phosphate bond joins adenosine diphosphate to form adenosine triphosphate.
