{'light waves': [0, 0, 1, 1], 'vacuum': [0, 1, 3, 7]}

The correct answer is option-1, which states that all three statements are correct.

Statement 1: Light waves can travel in a vacuum. This is true because light waves are a form of electromagnetic radiation, and they do not require a medium to propagate. This is why we can see the light from the sun, which is millions of kilometers away from us in the vacuum of space.

Statement 2: Light waves can be refracted. This is also true because when light waves pass from one medium to another with a different refractive index, they change direction. We can observe this phenomenon when light passes through a prism and it splits into different colors.

Statement 3: Light waves are electromagnetic. This statement is correct as light waves are a type of electromagnetic radiation. They consist of oscillating electric and magnetic fields that propagate through space.

So, all three statements are accurate, making option-1 the correct answer.
