**Going through my physics assignment tonight, so that's 10 questions I'll be posting. Since I'm thoroughly hopeless at this subject most of my attempts will be based on my elite google-fu or trawling through lecture notes, bear with me and thanks!**

1. Homework Statement

1. Homework Statement

frequency (f)=160hz

Force (F)=150 newtons

wavelength (λ)=0.40m

mass(m)=6 grams

find the length of a string with these properties

## Homework Equations

f(λ)=sqrt [F/(m/L)]

found this formula and the statement "solve for L" for this exact question online.

I put the values in above, I believe I interpreted them right.

## The Attempt at a Solution

It seemed a bit dodge to re-arrange, but i got L on it's own to be:

L= [F/(fλ ^2)]/m

(with values)

[150/(160x0.40)^2]/6=0.0061m...I have a feeling I may be off here XD.
