Two small identical speakers are connected (in phase) to the same source. The speakers are 3 m apart and at ear level. An observer stands 4 m in front of one speaker (at point X) as shown. The sound the observer hears will be least intense if the wavelength is: Speaker 1 * (a) 1 m, (b) 2 m, (c) 3 m, (d) 4 m, (e) 5 m. 3 m Speaker 2 *- 4 m X

Transcribed Image Text:**Interference and Sound Intensity Problem**
**Problem Statement:**
Two small identical speakers are connected (in phase) to the same source. The speakers are 3 meters apart and at ear level. An observer stands 4 meters in front of one speaker (at point X) as shown. Determine at which wavelength the sound the observer hears will be least intense.
**Diagram Explanation:**
- There are two speakers labeled as "Speaker 1" and "Speaker 2".
- The speakers are 3 meters apart.
- An observer is positioned at point X, which is 4 meters directly ahead of "Speaker 2".
**Possible Wavelengths:**
- (a) 1 meter
- (b) 2 meters
- (c) 3 meters
- (d) 4 meters
- (e) 5 meters
