Question 162: Dual Nature of Matter and Radiation

Question

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 :

Accepted Answer

$$\lambda  = {h \over p}$$
both the particles will move with momentum same in magnitude & opposite in direction.
So De-Broglie wavelength of both will be same i.e. ratio 1 : 1

Answer

1 : 3

Answer

3 : 1

Answer

1 : $$\sqrt 3 $$

Answer

1 : 1
