Answer :

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
