Electrons of energies 10.26 eV and 12.09...

Electrons of energies 10.26 eV and 12.09 eV can cause radiations to be emitted from hydrogen atoms. Find the maximum wavelength of the radiations if the electrons drop back to the ground state.

A

`1206Å`

B

`1020Å`

C

`1495Å`

D

`1617Å`

Text Solution

Verified by Experts

The correct Answer is:
A
`(hc)/lamda=E, lamda=(6.6xx10^(-34)xx3xx10^8)/(10.26 xx1.6 xx10^(-19))=1.206xx10^(-7)=1206Å`
