Answer:
0.033 m/s
Explanation:
The speed of the wave given only it's frequency and wavelength can be found by using the formula
[tex]c = f \times \lambda[/tex]
where
c is the velocity of the wave in m/s
[tex] \lambda[/tex] is the wavelength in m
f is the frequency in Hz
From the question we have
c = 15 × 0.0022 = 0.033
We have the final answer as
0.033 m/s
Hope this helps you
