# Confused about the speed of a wave

## Homework Statement

Actually its not a homework problem sort of thing.....I was wandering through a book , studying waves then I realised that there were two formula for the same thing .....the velocity of a wave.

## Homework Equations

v=λ/T [where λ is the wavelength and T is the time period]
V=√(T/μ) [where T is tension and μ is linear mass density]

## The Attempt at a Solution

I dont know.......are both of these correct and I am relating two different things ? or both of them are applied at different places .... I just dont get it....help needed.....[/B]

Edit: Is it like that velocity of a wave is defined by the second formula and the first formula is just a relation between λ and T where v is a constant .[ Just like in the case of resistance in dc circuits where R=ρl/A actually defines Resistance whereas V=RI is just a realtion between V & I where R is just a constant]
