Assertion : Partially transverse waves are possible on a liquid surface.
Reason : Surface tension provide some rigidity on a liquid surface.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

To solve the question regarding the assertion and reason, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
- **Assertion**: "Partially transverse waves are possible on a liquid surface."
- **Explanation**: Transverse waves are characterized by the motion of particles being perpendicular to the direction of wave propagation. On a liquid surface, waves can exhibit transverse characteristics due to the effects of surface tension. This means that while the primary motion of the wave is horizontal, there can be vertical oscillations of the liquid particles at the surface, which makes partially transverse waves possible.
- **Conclusion**: The assertion is **true**.

### Step 2: Analyze the Reason
- **Reason**: "Surface tension provides some rigidity on a liquid surface."
- **Explanation**: Surface tension is the cohesive force between liquid molecules at the surface, which creates a 'skin-like' effect. This tension does indeed provide some rigidity to the surface of the liquid, allowing it to support certain types of waves, including partially transverse waves.
- **Conclusion**: The reason is also **true**.

### Step 3: Determine the Relationship
- The assertion states that partially transverse waves can exist on a liquid surface, and the reason explains that this is due to the rigidity provided by surface tension.
- However, while both statements are true, the reason does not fully explain the assertion. The existence of partially transverse waves is not solely due to surface tension; other factors also contribute to wave behavior on liquid surfaces.

### Final Conclusion
- Both the assertion and the reason are true, but the reason is not the correct explanation for the assertion. Therefore, the answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Answer:
Both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
