Determine the wavelength of the wave

[keemosabi]

Homework Statement

A longitudinal wave with a frequency of 34 Hz takes 1.3 s to travel the length of a 2.5 m Slinky (see Figure 16.3). Determine the wavelength of the wave.

λ = _______ m

Homework Equations

v = λ f
v = d/t

The Attempt at a Solution

v = d/t
v = 2.5/1.3
v = 1.9

v = λ f
λ = v/f
λ = 1.9/34
λ = .05 m

What did I do wrong?

Try calculating with a little more precision?

I get an answer that is more than 10% from your calculation.

I guess that was the problem. I did my calculations again without any rounding, and it was marked as correct.

Thank you for your help. It is much appreciated.
