A partical of mass M at rest decays into two Particles of masses
`m_1 and m_2` having non-zero velocities. The ratio of the de - Broglie wavelengths
of the particles `lambda_1| lambda_2` is
(a) `m_1//m_2` (b)`m_2// m_1` (c ) 1 (d)`sqrt2 // sqrt1`

A

`(m_(1))/(m_(2))`

B

`(m_(2))/(m_(1))`

C

`1:1`

D

`sqrt((m_(2))/(m_(1)))`

Text Solution

Verified by Experts

The correct Answer is:
C

`lambda=(h)/(p)`
Since the momenta of the two particles are equal `lambda` are same.
