How Does Speaker Placement Affect Sound Frequency Detection?

AI Thread Summary
Speaker placement significantly influences sound frequency detection due to the phenomenon of sound interference. In the scenario, the student observes a quiet spot caused by the difference in distance from each speaker, indicating a phase difference. The speed of sound in the room is 350 m/s, and the distance between the speakers is 4.0 m, leading to calculations involving wavelength and frequency. The formula used to determine frequency is f = v/λ, where λ is derived from the path difference. Accurate calculations are essential for determining the frequencies being played by the speakers, highlighting the importance of precise speaker positioning in sound quality.

Hi I am having a rough time with this questoin .

Homework Statement


Question: A student enters Best Buy prepared to buy a pair of speakers. Before he does so, he conducts an experiment with them. He places the speakers 4.0 m apart and connects a signal generator to both speakers that produces a single and consistent tone. (constant wavelength and frequency) He then walks to a point that is 2.0 m from one speaker and 2.3 m from the other. At that point he notices a quiet “spot”. If the speed of the sound in the room is known to be 350 m/s, calculate the possible frequencies being played by the speakers.



Homework Equations


PD = (n-1/2) λ



The Attempt at a Solution


f = v/(lambda) = 350/6(2n + 1) = 58.33/(2n+1) ... n belongs to integer

350/6(2n + 1)
That denominator is not right. Try again. Take more care.
 
PD = (n-1/2) λ ... PD = 0.3

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
