Statement : wavelength of (I) line of Humphry series is more than (I) line of Lyman series in H-atom
Explanation : `Delta E = (hc)/( lambda)`.

Options

A. S is correct but E is wrong
B. S is wrong but E is correct.
C. Both S and E are correct and E is correct explanation of S
D. Both S and E are correct but E is not correct explanation of S

Answer

C

Explanation

` Delta E_1 = E_6 -E_5` in Humphry series and
`Delta E_2 =E_2 -E_2 -E_1` in Lyman seies
` :. Delta E_2 = E_2 - E_1 ` for Lyman series
` :. Delta E_2 gt Delta E_1`
` :. Delta _(Lyman ) lt Delta _("Humphry")` .
