Here's why:
* Electromagnetic waves are disturbances in electric and magnetic fields that propagate at the speed of light. They don't require a medium to travel, which is why they can move through the vacuum of space.
* Examples of electromagnetic waves include:
* Light
* Radio waves
* Microwaves
* X-rays
* Gamma rays
Other types of waves, like sound waves, need a medium to travel through. Sound waves are vibrations that travel through solids, liquids, or gases. They cannot travel through a vacuum.
