Textbook Question
Chapter 25.1, Problem 4TH
Consider the following incorrect statement referring to problem 3:
“A Pont A moves farther and farther away from the sources, the distances to the sources become more nearly equal, so the difference in distance is negligible. Thus the waves are move nearly in phase as Point A moves farther and farther away from the sources.”
What is the flaw in this argument? Explain your reasoning.

The acoustical system shown in the figure below is driven by a speaker emitting sound of frequency 730 Hz. (Use v = 343 m/s.)
If constructive interference occurs at a particular instant, by what minimum amount should the path length in the upper U-shaped tube be increased so that destructive interference occurs instead?m
(b) What minimum increase in the original length of the upper tube will again result in constructive interference?

Suppose that y1(x,t) and y2(x,t) are two independent wave functions, which describe the displacements vertical (in meters) of a string, as a function of position x (in meters) and time t (in seconds):
(See image)
For what values of the phase constant ϕ1 does destructive interference occur?
Compliment:
According to an article I've read on the internet, destructive interference occurs when ϕ1-ϕ2=180°
What I did was :
ϕ1+(π/3)=π
Is it wrong?

Each grid has two different waves (e.g., Wave and Wave B). Your goal is to draw the resulting wave (i.e., Wave C) if the two waves would have been superposed on top of each other. To do this, you'll need to add the two amplitudes (height of the Wave A and Wave B on the y-axis) at a given point on the x-axis to get the resulting one. For example, using number 3 as an example: a. At point 0 on the x axis, Wave A has an amplitude of 0, and Wave B has an amplitude of 0, so Wave C at point 0 would be 0. b. At point 4 on the x axis, Wave A has an amplitude of 6, and Wave B has an amplitude of 4, so Wave C at point 3 would have an amplitude of 10. c. At point 8 on the x axis. Wave A has an amplitdue of 0, and Wave B has an amplitude of -4, so Wave C at point 8 would be -4. You do not have to find the points for every single point along the x-axis, but just enough to get the general shape of the resulting wave. Once you…arrow_forward
