When a wave travels through a medium, particles are transferred from one place to another. Let's explore this in detail:

What is a Wave?
A wave is a disturbance that travels through a medium, transferring energy from one place to another. It can be described as a series of vibrations or oscillations that propagate through space.

Types of Waves:
There are two main types of waves: mechanical waves and electromagnetic waves. Mechanical waves require a medium to travel through, such as sound waves or water waves. Electromagnetic waves, on the other hand, can travel through a vacuum (empty space), such as light waves or radio waves.

How Waves Transfer Energy:
When a wave travels through a medium, it transfers energy in a periodic manner. This means that the particles of the medium vibrate back and forth around their equilibrium positions, without actually moving from one place to another. As the wave passes through the medium, the particles oscillate and transfer energy to neighboring particles, causing a ripple effect.

Particle Transfer in a Wave:
The correct answer to the given question is option 'C' - particles are transferred from one place to another. Although the particles of the medium do not move from one place to another, they do transfer energy to neighboring particles. This transfer of energy allows the wave to propagate through the medium.

Example:
Let's consider a water wave as an example. When a water wave travels through the ocean, the water particles themselves do not move horizontally across the ocean. Instead, they oscillate up and down or in circular motion as the wave passes through them. However, energy is transferred from one particle to another, allowing the wave to propagate.

So, in conclusion, when a wave travels through a medium, particles are not physically transferred from one place to another. Instead, they oscillate around their equilibrium positions and transfer energy to neighboring particles, enabling the wave to propagate.
