Homework Help Overview

The problem involves two microphones positioned at specific locations, with a sound source on the +x axis. The task is to determine the distances from the sound source to each microphone based on the time delay of sound reaching them.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculations for distances L1 and L2, with one participant providing a formula based on the speed of sound and time delay. Another participant questions the completeness of the answer, specifically regarding units of measurement.

Discussion Status

The discussion is active, with participants exploring the correctness of the calculations and the importance of specifying units. There is no explicit consensus on the final answer, as participants are still questioning aspects of the solution.

Contextual Notes

Participants are addressing potential oversight regarding the units of measurement for the calculated distances, which is critical for clarity in the problem context.

Homework Statement



One microphone is located at the origin, and a second microphone is located on the +y axis. The microphones are separated by a distance of D=1.5 m. A source of sound is located on the +x axis, its distances from microphones 1 and 2 being L1 and L2, respectively. The speed of sound is 343 m/s. The sound reaches microphone 1 first, and then .00146 s later, microphone 2. Find the distances L1 and L2


Homework Equations





The Attempt at a Solution



L1= x
L2= x + (343 * .00146)

1.5^2 + X^2 = (x+ (343*.00146))^2
x= 1.996

L1=1.996
L2=2.4968

The answer almost looks OK. You just forgot one thing...
 
i feel its perfectly ok..
please tell what he forgot
 
Units!

L1 = 1.996 lightyears? meters? yards? GeV-1?
