## Homework Statement

A particle A of mass m and initial velocity v collides with a particle B of mass m 2 which is at rest. The collision is head on, and elastic. The ratio of the de-Broglie wavelengths λA to λB after the collision is

## Homework Equations

u initial velocity

v final velocity

## The Attempt at a Solution

after collision

A->V-x

B->x

λA/λB=(h/m(v-x)) / (h/( m/2 x)) = 1/2x/v-x

momentum conservation--

mv=m(v-x)+ m/2(x)

v=v-x+x/2

x=0 !

now what??

I really don't understand anything and all sites do different solutions so please don't put my question in black hole.
