Question

wavelength of radiation emited when an electron ia a H like atoms jumps from a state A to C 2000 A^0 and it is 6000A^0 ,when the electron jumps from state B to C wavelength of the radiation emitted when an electron jumps from state A to B will be

Answer 1

Answer:

3024A^o

Explanation:

We see that energy emitted from the first transition is higher. Hence A is farther away from nucleus than B.

E=hc/lambda

a easy formula to calculate energy in eV,

Energy=12400eV/wavelength in A^o

[Ec-Ea]-[Ec-Eb]

=6.2-2.1 (by applying formula)

=4.1eV

wavelength=12400/4.1=3024A^o
