Explanation:


In this analogy, we are comparing "Waves" to "Air" and finding the corresponding relationship with "Ripples". To understand the relationship between these terms, we need to examine the characteristics and properties of each.

Waves:
- Waves are disturbances that travel through a medium, transferring energy from one point to another without displacing the medium itself.
- Waves can be found in various forms such as ocean waves, sound waves, light waves, etc.
- Waves are characterized by their wavelength, frequency, and amplitude.

Air:
- Air is a gaseous medium that surrounds the Earth.
- It is composed mainly of nitrogen, oxygen, carbon dioxide, and other gases.
- Air can transmit sound waves and support the propagation of various forms of energy.

Now, let's analyze the relationship between "Waves" and "Air":

Waves propagate through Air:
- Air is a medium through which sound waves, light waves, and other types of waves can travel.
- Sound waves, for example, require a medium to propagate, and air serves as a medium for sound transmission.

Ripples:
- Ripples are small waves or undulations that form on the surface of a liquid, often caused by the disturbance of the liquid.
- They are commonly observed in water bodies, such as ponds, lakes, and rivers.

Based on the relationship between "Waves" and "Air," we can infer that the corresponding relationship between "Ripples" and a medium would be "Water." This is because ripples are specifically associated with disturbances on the surface of water.

Therefore, the correct answer to the analogy "Waves : Air :: Ripples : ?" is option 'B' - "Water."
