The diagram below (not drawn to scale) shows a pair of speakers producing sound in phase (at the speakers). The frequency of the sound is 340 Hz. All distances are given in the table below. all angles that appear to be right angles are right angles. Is the interference at point B constructive or destructive? Is the interference at point C constructive or destructive? Is the interference at point D constructive or destructive?

I got everything else right except part c, no idea.
Two speakers, emitting identical sound waves of wavelength 1.4 m in phase with each other, and an observer are located as shown in the figure below. (Let x = 5.0 m, and y = 8.0 m.) At the observer's location, what is the path difference for waves from the two speakers? m Will the sound waves interfere constructively or destructively at the observer's location? constructive destructive Suppose the observer now...

Consider two sinusoidal waves (1 and 2) of identical wavelength ?, period T, and maximum amplitude A. A snapshot of one of these waves taken at a certain time is displayed in the figure below. (Figure 1) Let y1(x,t) and y2(x,t) represent the displacement of each wave at position x at time t. If these waves were to be in the same location (x) at the same time, they...

You are standing on one side of the street, and you hear sound coming from two different speakers. One speaker is 16m down the street on the same side of you. The other speaker is directly across the street from the first speaker. The street is 12m wide. Both speakers are broadcasting sound at 85Hz. (Assume the speed of sound is 340m/s). Write down the equations for constructive and destructive interference. What variables are you going to need to solve...

+ X-Ray Diffraction 25 of 30 > A Review Constants Periodic Table Part A X-ray diffraction can be used to obtain structural information of crystalline compounds. X-ray wavelengths are about the same size as the space between atoms in solids. X-rays aimed at a crystal are diffracted by the atoms in the crystalline lattice. This results in an X-ray diffraction pattern, which can be seen on a detector placed behind the crystal. X-rays with a wavelength of 1.58 A scatter...
