Which properties of a medium are responsible for propagation of wave through it ?

Answer

To determine the properties of a medium that are responsible for the propagation of waves through it, we can analyze the characteristics that allow waves to travel. Here’s a step-by-step solution:

### Step 1: Identify the properties of the medium
The first step is to recognize that certain physical properties of a medium are essential for the transmission of waves.

### Step 2: Discuss elasticity
The first important property is **elasticity**. Elasticity refers to the ability of a medium to return to its original shape after being deformed. This property allows the medium to transmit mechanical disturbances (waves) effectively.

### Step 3: Consider resistance
The second property is **low resistance**. A medium with low resistance allows waves to travel with minimal energy loss. High resistance would dampen the wave, reducing its amplitude and speed.

### Step 4: Include inertia
The third property is **inertia**. Inertia is the tendency of an object to resist changes in its state of motion. For wave propagation, inertia allows the medium to maintain the motion of the wave as it travels through the medium.

### Step 5: Summarize the properties
In summary, the properties of a medium that are responsible for the propagation of waves include:
1. **Elasticity** - the ability to return to original shape.
2. **Low Resistance** - minimal energy loss during wave travel.
3. **Inertia** - resistance to changes in motion.

### Final Answer
All these properties must be present in a medium for effective wave propagation.
