HELP IDK WHAT THIS IS
The property that is unique to electromagnetic waves is that they can travel in a vacuum.
To arrive at this answer, we can eliminate the options that are not unique to electromagnetic waves.
First, let's look at the option "They can be controlled by the pull of gravity." While it is true that all objects are influenced by gravity, including electromagnetic waves, this property is not unique to electromagnetic waves. Therefore, we can eliminate this option.
Next, let's consider the option "They can travel on the surface of water." While some waves, such as water waves, can travel on the surface of water, electromagnetic waves cannot. Electromagnetic waves can only travel through a medium (like air or space) or a vacuum, not on the surface of water. Therefore, we can eliminate this option as well.
Lastly, let's focus on the option "They can shake structures on Earth." While certain waves, like seismic waves, can shake structures on Earth, this property is not unique to electromagnetic waves. Other types of waves, such as sound waves and mechanical waves, can also shake structures. Hence, we can eliminate this option too.
This leaves us with the final option, "They can travel in a vacuum." This is the correct answer because electromagnetic waves are able to propagate through a vacuum, such as in space, where there is no medium to transmit the wave. None of the other options describe a property unique to electromagnetic waves.
