Standing Wave in String and Organ Pipe: Practice Problem & Solution
Assertion (A): Sound produced by an open organ pipe has good quality than sound produced by a closed organ pipe. Reason (R): In OOP both even & odd harmonics are present.
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Standing Wave in String and Organ Pipe. Understanding the underlying formula is key to arriving at the correct answer below:
The sound quality of an instrument depends on the number and intensity of overtones present. Because open organ pipes produce a full series of both even and odd harmonics, they generate a richer, higher-quality sound compared to closed pipes, which only produce odd harmonics. Therefore, both (A) and (R) are true, but (R) describes the richness of the open pipe rather than serving as the direct reason for the comparison.
