Plzzz give me the right answer
The correct answer is sound waves, because they travel by oscillating molecules.
The correct answer is: sound waves, because they travel by oscillating molecules.
To determine the correct answer, we need to understand what a wave is and how it propagates. A wave is a disturbance that carries energy from one location to another. Waves can be classified into two main types: mechanical waves and electromagnetic waves.
Mechanical waves, such as sound waves, require a medium to travel. A medium is a substance or material that the wave can pass through. In the case of sound waves, they travel by oscillating (vibrating) molecules in the medium. For example, in air, sound waves travel by causing the air molecules to vibrate in a back-and-forth motion. Therefore, sound waves need a medium like air, water, or solid objects to propagate.
On the other hand, electromagnetic waves, such as light waves, do not require a medium to travel. They can propagate through a vacuum (empty space) and do not rely on oscillating molecules. Instead, electromagnetic waves consist of oscillating electric and magnetic fields that can transport energy. Examples of electromagnetic waves include visible light, radio waves, microwaves, and X-rays.
So, the correct answer is sound waves, because they travel by oscillating molecules.
