$0.01 m$

#### Explanation:

We know for sonic and ultra sonic waves the velocity $v$ is related to frequency $n$ and wavelength $\lambda$ by the following expression

$v = n \lambda$

Inserting given values we get
$1500 = 0.15 \times {10}^{6} \lambda$
$\lambda = \frac{1500}{0.15 \times {10}^{6}}$
$\lambda = 0.01 m$
