Question
A point source of sound is located somewhere along the x-axis. Experiments show that the same wave front simultaneously reaches listeners at x = –8 m and x = +2.0 m.
A third listener is positioned along the positive y-axis. What is her y-coordinate (in m) if the same wave front reaches her at the same instant as it does the first two listeners?
Options
A.4
B.3
C.2
D.5
Solution
Sol. The source must be at mid point of x = – 8 and x = 2, i.e. source is at x = – 3
Distance between x = 2 & source is 5
For y = 4, Distance from source will be same
