Particle A of mass moving along the axis with velocity
collides eleastically with another particle B at rest having mass
. If both particles move along the x-axis after the collision, the change
in de-Brogile wavelength of particle A, in terms of its de-Brogile wavelength
before collision is:
Option: 1
Option: 2
Option: 3
Option: 4
Applying momentum conservation
Since, collision is elastic (e=1)
From equation (1) and (2)
we get
Now, De-Broglie wavelength of A before collision:
Final De-Broglie wavelength
