what do all electromagnetic waves have in common?\no they can travel at the speed of light.\no they have the same wavelengths.\no they travel only through matter.\no they have nonmoving magnetic fields.
Answer
Brief Explanations:
Electromagnetic waves in a vacuum all travel at the speed of light ($c = 3\times10^{8}\ m/s$). They have different wavelengths depending on the type (e.g., radio - waves have long wavelengths, gamma - rays have short wavelengths). They can travel through a vacuum as well as matter. And they have oscillating electric and magnetic fields.
Answer:
They can travel at the speed of light.
