Question

can electromagnetic waves travel in a vacuum (empty space/no medium)? yes no

Explanation:

Electromagnetic waves are composed of electric and magnetic fields that oscillate perpendicular to each other and to the direction of wave propagation. They do not require a medium (like air or water) to travel. This is in contrast to mechanical waves (such as sound waves), which rely on particles of a medium to transfer energy. In a vacuum, there are no particles, but electromagnetic waves can still propagate because they are self - sustaining oscillations of electric and magnetic fields. For example, light (which is an electromagnetic wave) travels from the Sun to the Earth through the vacuum of space.

Answer:

yes
