Particle A of mass mA=

m

2

moving along the x-axis with velocity v0 collides elastically with another particle B at rest having mass mB=

m

3

.
If both particles move along the x-axis after the collision, the change Δλ in de-Brogliewavelength of particle A, in terms of its de-Broglie wavelength (λ0) before collision is :
