## Homework Statement

just wondering how we got T when the equation is V=

**f**

**λ i assume that this is one oscillation.**T=4.5x10-4

F=?

**λ= 2.0x10⁵cm**

## Homework Equations

V=f

**λ**

F=1/T

F=1/T

## The Attempt at a Solution

F=1/4.5x10-4

F=22 hz

v= f

**λ**

v= (22) (2.0x10⁵)

v= (22) (2.0x10⁵)

v=4400000 m/s
