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.
