Answer:
Explanation:
The frequency formula in terms of wavelength and wave speed is given as
[tex] \sf f = \dfrac{\nu}{\lambda}[/tex]
where,
- [tex]\nu[/tex] is the wave speed in m/s, and
- λ is the wavelength of the wave in m
Wave speed can be calculated by,
⇒️ Speed = distance/time
⇒️ speed = 10 m/5 seconds
⇒️ speed = 2 m/s
So, the speed of the wave is 2 m/s
Now,
⇒️ [tex]\sf f = \dfrac{\nu}{\lambda}[/tex]
⇒️ [tex]\sf f = \dfrac{2 }{1.5}[/tex]
⇒️ [tex]\sf f = 1.33 \ Hz [/tex]
Therefore, the frequency of the water wave is 1.33 Hz
