4. You are standing 4.0 m in front of a speaker, which is 3.0 m away from the other speaker on aline perpendicular to your line with the first speaker (see diagram below). They are playing a 688Hz sinusoidal tone in phase. Assume the speed of sound is 344 m/s. Are you at a node, anantinode or some other point? Show a calculation that proves your point (hint: is a node a pointof constructive or destructive interference?).3.0 m1923niटर

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.

Item 6 Learning Goal: To understand standing waves, including calculation of X and f, and to learn the physical meaning behind some musical terms. The columns in the figure (Figure 1) show the instantaneous shape of a vibrating guitar string drawn every 1 ms. The guitar string is 60 cm long. The left column shows the guitar string shape as a sinusoidal traveling wave passes through it. Notice that the shape is sinusoidal at all times and specific features, such as the crest indicated with the arrow, travel along the string to the right at a constant speed. The right column shows snapshots of the sinusoidal standing wave formed when this sinusoidal traveling wave passes through an identically shaped wave moving in the opposite direction on the same guitar string. The string is momentarily flat when the underlying traveling waves are exactly out of phase. The shape is sinusoidal with twice the original amplitude when the underlying waves are momentarily in phase. This pattern is called a…
