Answer:
<h2>109.52 Hz</h2>
Explanation:
The frequency of the wave when given it's velocity and wavelength only can be found by using the formula

where
c is the velocity of the wave in m/s
is the wavelength in meters
From the question we have
c = 230 m/s
= 2.1 m

We have the final answer as
<h3>109.52 Hz</h3>
Hope this helps you
