A particle of mass 4M at rest disintegrates into two particles of mass M and 3M, respectively, having non zero velocities. The ratio of de-Broglie wavelength of particle of mass M to that of mass 3M will be:
  1. 1:3
  2. 3:1
  3. 1:3
  4. 1:1

Solution

λ=hp

Both the particles will move with momentum same in magnitude and opposite in direction.

So de Broglie wavelength of both will be same, i.e., ratio 1:1.
