Particle$\mathrm{A}$of mass${\text{m}}_{\text{A}}=\frac{\text{m}}{2}$moving along the$\text{x}$-axis with velocity${\text{v}}_0$collides elastically with another particle$\text{B}$at rest having mass${\text{m}}_{\text{B}}=\frac{\text{m}}{3}$. If both the particles move along the$\text{x}$-axis after the collision, the change$∆\lambda$in the wavelength of the particle$\text{A}$, in terms of its de-Broglie wavelength$\left({\lambda }_0\right)$before the collision is:
