What do all electromagnetic waves have in common? they can travel at the speed of light. they have the same wavelengths. they travel only through matter. they have nonmoving magnetic fields.

They all travel at the speed of light.

They can travel at the speed of light.

Explanation:

Electromagnetic waves can travel via space as well as matter. These waves travel at the speed of light in space and slow down in medium. Electromagnetic waves do not require medium to travel.

Electromagnetic waves are composed of electric and magnetic fields perpendicular to each other. These fields generate each other and this way the wave carries forward the energy. The electromagnetic wave moves in the direction perpendicular to both electric field and magnetic field.
