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
