The frequency of emission line for eny ...

The frequency of emission line for eny transition in positronium atom (consisting of a positron and an electron) is `x` times the frequency of the corresponding line in the case of `H` atom , where `x` is

A

`sqrt2`

B

`1//2 sqrt2`

C

`1//2 sqrt2`

D

`1//2`

Text Solution

Verified by Experts

The correct Answer is:
D
Rydberg's constant determine the frequency. We have `R prop m` So , modified `R` for positronium atom is half of `H` atom. Hence, frequency are reduced to half.
