ANSWER:
0.38 meters.
STEP-BY-STEP EXPLANATION:
Given:
The speed of sound in air (v) = 340 m/s
Frequency (f) = 903 Hz
We calculate the wavelength using the following formula:
[tex]\begin{gathered} \lambda=\frac{v}{f} \\ \\ \text{ We replacing:} \\ \\ \lambda=\frac{340}{903} \\ \\ \lambda=0.37652\cong0.38\text{ m} \end{gathered}[/tex]The wavelength is equal to 0.38 meters.
