Answer:

4.4721m

Explanation:

#Use Pythagorean theorem to find the distance between the two speakers:

$a^+b^2=c^2\\4^2+2^2=d^2\\\sqrt{20}\ mm=d$

There are antinodes 1/4,1/2 and 3/4 of the distance between speakers.

The greatest antinode is 3/4-1/4=1/2

#Distance between consecutive antinodes is:

$0.5\times \sqrt{20}=\lambda/2\\\\\lambda=4.4721m$

Hence, the maximum possible wavelength of the sound waves is 4.4721m
