Question

Constructive and Destructive Interference of Sound Waves Two cellists, one seated directly behind the other in an orchestra, play the same note for the conductor, who is directly in front of them. Because of the separation between the cellists, destructive interference occurs at the conductor. This separation is the smallest that produces destructive interference. Would this separation increase, decrease, or remain the same if the cellists produced a note with a higher frequency? The separation between the cellists would remain the same. The separation would decrease because the wavelength of the sound is greater. The separation would decreased became the wavelength of the sound is smaller. The separation would increase because the wavelength of the sound is greater. The separation would increase because the wavelength of the sound is smaller. Diffraction A loudspeaker is producing sound of a certain wavelength. Which combination of the wavelength lambda (expressed as a multiple of lambda 0) and the speaker's diameter D (expressed as a multiple of D0) would

Explanation / Answer

Because the seperation would be decrease because the wavelength of the sound is smaller hence frequency is increases . Frequency and wavelength are inveresly proportional. so the distance decreases hence constructive interference takes place.
Hence the answer is C .
