# Calculating the frequency of a wave

#### tascja

1. Homework Statement
A snapshot graph of a travelling wave is shown. The wave is travelling to the right at 44.0 m/s. the maximum displacement is 18.0 cm and the total distance travelled by the wave is 28.0 m
What is the frequency?

2. Homework Equations
3. The Attempt at a Solution
total distance traveled/ # ticks = 28 m/10 = 2.8m/tick

There are 7 ticks in one wavelength

7*2.8 = 19.6 m

Do a recount. Once you find the wavelength, how do you calculate the frequency?

#### tascja

now it works, thanks :)
** 6 ticks to a wavelength, making it 16.8 m

and then frequency = c/lamba
= 44/16.8
= 2.6 Hz
