Statement : wavelength of (I) line of Hu...

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

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `Delta E_1 = E_6 - E_5` in Humphrey series and `Delta E = E_2 - E_1` for Lyman series
`because Delta E gt Delta E_1`
`lamda_(Lyman) lt lamda_(Humphry)`.
