Question

A set of water waves travels at 10.0 m/s, and 5.0 waves pass you in 2.0 s. What is the wavelength of the waves?

Answer 1

I know the answer is 4.0m i just need it explained to me how that answer came about

Answer 2

v = a.f
v = velocity
a= the wavelength
f = frequency aqual she spreads

Answer 3

How would the equation look

Answer 4

finding the frequency
5 --- 2
x --- 1
2x = 5
x = 5/2
x = 2.5

10 = a.f
10 = a.2,5
a = 10/2,5
a = 4

Answer 5

ok thank you that helps
