The correct answer is B. Light. Here's why: - Light is a form of electromagnetic radiation. Electromagnetic waves don't need a medium (like air or water) to travel. They can travel through the vacuum of space, as we see with sunlight reaching Earth. Let's look at the other options: - Ocean waves are mechanical waves. They require a medium (water) to propagate.- Sound is also a mechanical wave. It requires a medium (like air) to travel.- Earthquakes create seismic waves, which are mechanical waves that travel through the Earth's crust. Key takeaway: Light is the only wave in the options that can travel without a medium.
