Answer:
[tex] \huge{ \boxed{4 \: m}}[/tex]
Explanation:
The wavelength of the wave given it's speed and frequency can be found by using the formula
[tex] \lambda = \frac{v}{f}\\ [/tex]
where v is the speed
f is the frequency
From the question
v = 12 m/s
f = 3 Hz
We have;
[tex] \lambda = \frac{12}{3} = 4 \\ [/tex]
We have the final answer as
4 m
