QUESTION:
Problem 27E
If the distance from a bugle is tripled, by what factor does the sound intensity decrease? Assume that no reflections affect the sound.
ANSWER:
Solution 27E
Step 1:
The intensity of the sound waves and the distance is related by the mathematical equation,
I = P / 4𝛑 r2
Where, P - Power generated by the source of sound
r - Distance which it travels.
So, the only thing which will influence the intensity will be the distance “r”.
