Question

how are electromagnetic waves different than all other waves?
they can be transmitted.
they can be reflected.
they can vibrate matter.
they can travel through space.

Explanation:

Electromagnetic waves are unique as they do not require a medium (like matter) to propagate. They can travel through the vacuum of space. Other types of waves (e.g., sound waves) need a medium (such as air, water, or solids) to vibrate and move. Transmitting (A) and reflecting (B) are properties many waves share. Vibrating matter (C) is more characteristic of mechanical waves which rely on a medium.

Answer:

D. They can travel through space.
