NEET Physics Question - Waves - Principle of Superposition, Interference and Beats

Assertion (A): Interference can happen in sound waves.

Reason (R): In Quincke's tube, interference is present due to initial phase difference as well as the phase difference due to path difference.

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

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

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

(4) Both (A) and (R) are false

Solution:

Sound waves, being waves, exhibit interference. Thus, Assertion (A) is true. In Quincke's tube, interference is primarily due to path difference. An initial phase difference is not typically considered in a standard setup. Therefore, Reason (R) is false.
