Two students in a dorm room listen to a pure tone produced by two loudspeakers that are in phase. Students A and B in Figure 28–32 hear a maximum sound. What is the lowest possible frequency of the loudspeakers?

Figure 28–32

Step-by-Step Solution:

Solution 5P

Step 1 of 2

Here, we have to calculate the lowest possible frequency.

The equation for the path difference is,

We have to calculate the distance of the student B from the left source. Consider this as a right angled triangle of base 3.0 m and height 1.5 m.

Therefore, the hypotenuse,

That is,
