What is the smallest separation between the violinists that will produce destructive interference for the listener?
IP Two violinists, one directly behind the other, play for a listener directly in front of them. Both violinists sound concert A (440 Hz).
Part A
What is the smallest separation between the violinists that will produce destructive interference for the listener?
Part B
Does this smallest separation increase or decrease if the violinists produce a note with a higher frequency?
increases
decreases

Two speakers, which are separated by a distance d,
produce sound waves with the same amplitude, phase and frequency.
The frequency of the sound is 570 Hz. You stand a distance of 3.50
m directly in front of the left speaker, on the dashed line shown
in the diagram. Assume the speed of sound to be 340 m/s. What is
the smallest possible value of d so that you hear no sound
because of destructive interference?

To understand the cause of constructive and destructive interference for the double-slit experiment, and to explain how the interference pattern depends on the parameters of the emitted waves. For this tutorial, use the PhET simulation Wave Interference. This simulation allows you to send waves through a variety of barriers and look at the resulting interference patterns. Start the simulation. You will see three possible selections: Waves, Interference, and Slits. To change between simulations at any point, select the desired simulation...

1. (28 Points) Symphony halls are designed to reduce the number of locations that produce intensity minima from reflections by the wall. In this problem you are asked to compute the frequencies that produce intensity minima if the room has bare concrete walls. Imagine a source of sound (S) that is played at the front stage of a symphony hall. A listener (L) is standing next to the cheap seats at the back of the hall. For simplicity let's assume...

I know how to do the first 3 parts. Need last 3 parts of the question. Posted whole thing for reference. Thanks! a) A 1 meter long guitar string of linear mass density 2g/m3 is put under tension until it resonates with a fundamental frequency of 440 Hz. Determine the tension that produces this fundamental frequency. Also determine the other of the first four harmonic frequencies and draw diagrams illustrating what each of these oscillations looks like on the string....

You are driving south on a road at a speed of 21.3 m/s and you hear a siren from a police car at a frequency of 915 Hz, as the police car approaches you while driving north. If the police car is going at a speed of 32.4 m/s, and the speed of sound is 343 m/s, what frequency would...

In this homework, you will be using a sound simulation. We will demonstrate this simulation in class. If the simulation is too difficult to install on your computer, do not worry, you should still be able to answer the questions. It is important to know that a lighter shade of gray in the simulation indicates an increase in pressure compared to the undisturbed air pressure and a darker shade indicates an decrease in pressure. The simulation is available online from...
