We know, Frequency = speed / wavelength
f = 341 / 0.8
f = 426.25 Hz
In short, Your Answer would be 426.25 Hz
Hope this helps!
<span>The amount of dissolved oxygen in water may decrease
because of the increase in organic matter in the water. <span>Aquatic organisms breathe and use oxygen. Large amounts of
oxygen are consumed by the decomposition of bacteria (when there are large
