A) 13.6eV
B) 20.4 eV
C) 34.0eV
D) 6.8eV
Correct Answer: B
Solution :
Energy in ground state =13.6 eV Energy absorbed \[=1.5\times 13.6\text{ }eV=20.4\text{ }eV\] Energy in higher level = 34.0 eV Energy emitted \[=34.0-13.6=20.4\text{ }eV\] KE to the emitted electron = 20.4 eVYou need to login to perform this action.
