The time taken by an electron to go from ground state to excited state in one shake (one shake `=10^(-8)s`). Find this tijme is nanosecond.

A

`10ns`

B

`4ns`

C

`2ns`

D

`25ns`

Text Solution

Verified by Experts

(a) `:.n_(1)u_(1)=n_(2)u_(2)`
`1xx"shake"=n_(2)s`
or `10^(-8)s=n_(2)s`

In a sample of H-atoms in ground state electrons make transition from ground state to a particular excited state where path length is 5 times de Broglie wavelength , electrons make back transition to the ground state producing all possible photons. If photon having 2nd highest energy of this sample can be used to excite the electron in a particular excited state of Li^(2+) ion then find the final excited state of Li^(2+) ion .
