A molecule of O_(2) and that of SO_(2) travel with the same velocity. What is the ratio of their wavelengths ?

A molecule of O_(2) and that of SO_(2) travel with the same velocity.

1.	A molecule of O_(2) and that of SO_(2) travel with the same velocity. What is the ratio of their wavelengths ?
Answer» Solution :`lamda_(O_(2))//lamda_(SO_(2)) = 2` (because `lamda = (H)/(MV) " i.e., " lamda prop (1)/(m)` and mass of `SO_(2)` molecule viz. 64 u, is DOUBLE than that of `O_(2)` molecule viz. 32 u)
