Problem

- Particle A of mass

m_A = \frac{m}{2}

moving along the x-axis with velocity

v_0

collides elastically with another particle B at rest having mass

m_B = \frac{m}{3}

. If both particles move along the x-axis after the collision, the change

\Delta\lambda

in de-Broglie wavelength of particle A, in terms of its de-Broglie wavelength (

\lambda_0

) before collision is : (1)

\Delta\lambda = \frac{3}{2}\lambda_0

(2)

\Delta\lambda = \frac{5}{2}\lambda_0

(3)

\Delta\lambda = 2\lambda_0

(4)

\Delta\lambda = 4\lambda_0
