Problem 1: The figure below shows four identical point sources of sound that are uniformly spaced on anx-axis.Sqd-dS3dS4PThe sources emit sound at the same wavelength X and same amplitude A, and they emit in phase. A pointP is shown on the x axis. Assume that as the sound waves travel to P, the decrease in their amplitude isnegligible. What multiple of A is the amplitude of the net wave at P if distance d in the figure is (a) X/4,(b) A/2, and (c) X?

The plots below show the displacement (y) with position (x) at some instant in time for two individual waves. Sketch the waveform that would be observed if these two waves coexisted (interfered). Is the result an example of constructive (superposition) or destructive interference? If these were sound waves, describe the relative loudness of the resultant wave relative to the initial waves.

Two loudspeakers emit identical sound waves along the x-axis. The sound at a point on the axis has maximum intensity when the speakers are 22 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 33 cm. Part A What is the wavelength of the sound? Part B If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

Weber's law states that the smallest detectable change in the sound stimulus for a wideband or bandpass filtered noise is proportional to its magniture c. Steven's power law states that the smallest detectable change in the sound stimulus for a wideband or bandpass filtered noise is inversely proportional to its magniture d. Weber's law states that loudness is inversley proportional to I1/3
Two identical point sources are generating waves with the same frequency and amplitude. The two sources are in phase with each other, so the two sources generate wave crests at the same instant. The wavelength of the waves is equal to the distance between the two sources. A. List all the labeled points where the waves from the two sources constructively interfere. If there are no such points, indicate that by stating "none". Separate each letter with a space. Hint: Determine the difference in the distance that each wave travels from the point sources. For example the difference between the distance travelled to B = 1.5λ - 0.5λ. Constructive interference occurs at ΔL=nλ. Destructive occurs at ΔL=nλ/2. B. List all the labeled points where the waves from the two sources destructively interfere. If there are no such points, indicate that by stating "none". Separate each letter with a space. Hint: Constructive occurs at ΔL=nλ. Destructive occurs at L=ΔL=nλ/2.
