A particle at rest explodes into two fragments of masses $$m_1$$ and $$m_2$$ ($$m_1 > m_2$$) which move apart with nonzero velocities. If $$\lambda_1$$ and $$\lambda_2$$ are their de Broglie wavelengths respectively, then

A

$$\lambda_1 > \lambda_2$$

B

$$\lambda_1 < \lambda_2$$

C

$$\lambda_1 = \lambda_2$$

D

data insufficient
