Statement I: waves genrated in a metal piece can be transverse or longitudinal.
statement II: waves generated depend upon the method of creating waves in the metal.

Options

A. Statement I is true, statement II is true and statement II is the correct explaination for statement I.
B. Statement I is true, statement II is true and statement II is NOT the correct explaination for statement I.
C. Statement I is true, statement II is false.
D. Statement I is false, statement II is true.

Explanation

To solve the question, we need to analyze both statements provided:

**Step 1: Analyze Statement I**
- Statement I claims that "waves generated in a metal piece can be transverse or longitudinal."
- In physics, waves can be classified into two main types: transverse waves and longitudinal waves.
- Transverse waves are those in which the particle displacement is perpendicular to the direction of wave propagation (e.g., waves on a string), while longitudinal waves are those in which the particle displacement is parallel to the direction of wave propagation (e.g., sound waves).
- In metals, both types of waves can indeed be generated depending on how the waves are initiated. For example, if you strike a metal bar, longitudinal waves (compression waves) can travel through it. If you vibrate the bar, transverse waves can also be created.
- Therefore, Statement I is **true**.

**Step 2: Analyze Statement II**
- Statement II states that "waves generated depend upon the method of creating waves in the metal."
- This statement is also true because the method used to generate waves affects the type of wave produced. For instance, if you apply a force along the length of the metal, you will generate longitudinal waves. If you apply a force perpendicular to the length, transverse waves will be generated.
- Thus, the type of wave generated indeed depends on the method of creating the waves.
- Therefore, Statement II is also **true**.

**Step 3: Determine the relationship between the statements**
- Since both statements are true, we need to determine if Statement II provides a correct explanation for Statement I.
- Statement II explains that the type of wave generated (transverse or longitudinal) is dependent on how the waves are created, which directly supports Statement I.
- Therefore, Statement II is the correct explanation for Statement I.

**Final Conclusion:**
- Both statements are true, and Statement II is the correct explanation for Statement I.

Thus, the answer is: **Statement I is true, Statement II is true, and Statement II is the correct explanation for Statement I.**
