Question

Assertion (A): As the level of water in a tall measuring cylinder kept under running tap rises, the pitch of sound gradually increases.

Reason (R): Frequency of sound is inversly proportional to the length of the water column.

पर्याय

• Both (A) and (R) are true and (R) is correct explanation of (A).

• Both (A) and (R) are true and (R) is not the correct explanation of (A).

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

(A) is true but (R) is false.

Explanation:

As the height of the air column decreases with increasing water column, the frequency increases, thereby raising the pitch of the sound; hence, the assumption is accurate. The assertion is incorrect, as the frequency of sound is inversely related to the length of the air column, not the water column.
