Question

In a sonometer, the waves produced are

• A. longitudinal progressive
• B. transverse progressive
• C. transverse, stationary and polarised
• D. transverse, stationary and unpolarised

Answer 1

The correct option is C

transverse, stationary and polarised

Sonometer: It is a device used to demonstrate the relationship between frequency and the length, tension, and mass per unit length of the string.

1. Sonometer consists of two fixed wedges.
2. And whenever a wave is produced between two fixed edges, the waves produced are transverse and stationary.
3. As the direction is only in one direction in the string, it is polarized.
4. The nature of waves produced is:

Hence, option C is the correct option.
