Arrange the wavelengths (a) of the following emission lines of H-atom in an increasing order. (1) n = 3 overset(lambda_(1))ton = 1 (2) n = 5 overset(lambda_(2))to n = 3 (3)n = 12 overset(lambda_(3))to n = 10(4) n = 22 overset(lambda_(4)) to n = 20

Answer»

`lambda_(4) lt lambda_(3) lt lambda_(2) lt lambda_(1)`
`lambda_(1) lt lambda_(2) lt lambda_(3) lt lambda_(4)`
`lambda_(1) lt lambda_(2) lt lambda_(4) lt lambda _(3)`
`lambda_(1)lt lambda_(3)ltlambda_(3) lt lambda_(4) lambda_(2)`

SOLUTION :When electron comes in a LOWER from higher orbit ENERGY is released, no MATTER from which higher orbit the electron is coming. Hence, `lambda_(1) ,lt lambda_(2) ltlambda_(3)lt lambda_(3) lt lambda_(4)`.
