**[SOLVED] Out of Phase waves**

## Homework Statement

Straight line AB connects two point sources that are 5.00m apart, emit 300Hz sound waves of the same amplitude, and emit exactly out of phase. (a) What is the shortest distance between the midpoint of AB and a point on AB where the interfering waves cause maximum oscillation of the air molecules? What are the (b) second and (c) third shortest distance?

## Homework Equations

and## The Attempt at a Solution

(delta L)/(wavelength) = .5, 1.5, 2.5 ...

(wavelength) = v/f = (velocity of molecules in the air)/f = 330/300 = 1.1m <- I don't think . that is right

(delta L) = (2.5 + x) - (2.5 - x) = 2.5 + x - 2.5 + x = 2x

I am I approaching this right, if not do you have any suggestions to sat me straight.
