Light and heat waves

They both are electromagnetic & can travel through vac., sound waves does not include in EM Spectrum

So, option A is your answer.

Hope this helps!

Answer: 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.
