In the figure, sound with a 15.3 cm wavelength travels rightward from a source and through a tube that consists of a straight portion and a half-circle. Part of the sound wave travels through the half-circle and then rejoins the rest of the wave, which goes directly through the straight portion. This rejoining results in interference. What is the smallest radius r that results in an intensity minimum at the detector? (Take the speed of sound to be 343 m/s.)

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

Current Attempt in Progress
In the figure, sound with a 15.3 cm wavelength travels rightward from a source and through a tube that consists of a straight portion
and a half-circle. Part of the sound wave travels through the half-circle and then rejoins the rest of the wave, which goes directly
through the straight portion. This rejoining results in interference. What is the smallest radius r that results in an intensity minimum at
the detector? (Take the speed of sound to be 343 m/s.)

Sound with a 29 cm wavelength travels rightward from a source and through a tube that consists of a straight portion and a half-circle. Part of the soundwave travels through the circle and rejoins the the rest of the wave which goes directly through the straight portion. This rejoining results in interference. What is the smallest radius r (in cm) that results in an intensity minimum at the detector. The maximum destructive interference will occur when the difference in the distance travelled by the two waves is 1/2 of a wavelength. To solve this problem express the difference in the distance travelled by the two waves as a function of r and set this amount equal to 1/2 of a wavelength.
