Step-by-step explanation:
The relation between frequency, wavelength, and velocity is as follows.
 

 where, f = frequency
 v = velocity
 
 = wavelength
 = wavelength
It is given that frequency of the wave is 230 hertz (or 230 per second) and velocity of wave is 460 m/s. Therefore, calculate the wavelength as follows.
 

or, 

 = 

 = 2 m
Therefore, we can conclude that the wavelength of the wave is 2 m.
