Answer:
ν=293.53 Hz
Step-by-step explanation:
ν= speed/λ
speed = 204 m/s
λ=0.695 m
v = 204 m/s * 1/0.695m
meters cancels out
1/s = Hz
v = 204/0.695 Hz
ν=293.53 Hz
please give thanks, click heart! :)
apparently it is wrong, but my work and online calculator says otherwise... possibly round your answer? I'm not sure then...
