## Homework Statement

The speed of a transverse wave on a string is 420 m/s, and the wavelength is 0.14 m. The amplitude of the wave is 1.5 mm. How much time is required for a particle of the string to move through a total distance of 1.0 km?

## Homework Equations

λ x υ= v

## The Attempt at a Solution

λ x υ= v

υ= v/λ= 420/0.14= 3000

(1000meters)/(0.00152)= (4.444 x 108) T, where T is the period

t= (4.444 x 108)/ 3000= 1.481 x 10^5

i dont get what i'm doing wrong :(
