NEET Physics Question - Waves - Standing Wave in String and Organ Pipe

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.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

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.
