which are characteristics of electromagnetic waves? check all that apply. they travel only through matter. waves with a higher frequency have a shorter wavelength. waves with a higher frequency have a longer wavelength. they all move at the same speed. they can travel through space.

Answer

Brief Explanations:

Electromagnetic waves can travel through a vacuum (space) and not just through matter. The relationship between frequency ($f$) and wavelength ($\lambda$) is given by $c = f\lambda$ (where $c$ is the speed of light in vacuum), so higher - frequency waves have shorter wavelengths. All electromagnetic waves travel at the speed of light in vacuum.

Answer:

Waves with a higher frequency have a shorter wavelength. They all move at the same speed. They can travel through space.
