Answer:
Frequency of wave = 3 Hertz
Step-by-step explanation:
Given that:
Wavelength of wave = 20 meters
Velocity of wave = 60m/s
We know that:
v = fλ
Here,
v = velocity , f = frequency and λ = wavelength
Putting values in formula
60 = f(20)
20f = 60
Dividing both sides by 20
[tex]\frac{20f}{20}=\frac{60}{20}[/tex]
f = 3 Hertz
Hence,
Frequency of wave = 3 Hertz
