Question

which of the following best describes electromagnetic waves?
electromagnetic waves can only transfer energy though water.
electromagnetic waves require the presence of a medium to be able to transfer energy.
electromagnetic waves can transfer energy through empty space.

Explanation:

Electromagnetic waves are a form of energy that can travel through a vacuum (empty space) without the need for a medium like water or air. This is a fundamental property of electromagnetic waves, differentiating them from mechanical waves (e.g., sound waves) which do require a medium.

Answer:

Electromagnetic waves can transfer energy through empty space.
