The speaker depicted below (See slide 10  of chapter 16 for a detailed explanation) emits a sound of frequency 779 Hz. Due to the path difference (r2 - r1) the receiver detects a constructive interference. Find the distance by which r2 needs to be adjusted to detect the very next destructive interference. (Take speed of sound as 343 m/s).

The speaker depicted below (See slide 10  of chapter 16 for a detailed explanation) emits a sound of frequency 779 Hz. Due to the path difference (r2 - r1) the receiver detects a constructive interference. Find the distance by which r2 needs to be adjusted to detect the very next destructive interference. (Take speed of sound as 343 m/s).

A sound wave from the speaker (S) propagates into the tube and splits into two parts at point P. Path length r2 S Path length r1 The two waves, which combine at the opposite side, are detected at the receiver (R).
