Two speakers 14 m apart are emitting tones at a frequency of 1020 Hz. What is the
closest distance (in m) from one speaker, along the line connecting the speakers, at
which the sound intensity be will be zero?
V= Lambda x f
The Attempt at a Solution
i tried this so far, but i dont have the correct answer. (it is .5 m)
x (minimum distance x, not known)
Delta L= 14-2x
lambda = (343 m/s) / 1020 Hz
lambda= .33627 m.
i dont know what to do now. Please help me
