Published on: August 13, 2026

Given below are two statements :
Statement I: When an electric discharge is passed through gaseous hydrogen, the hydrogen molecules dissociate and the energetically excited hydrogen atoms produce electromagnetic radiation of discrete frequencies.
Statement II: The frequency of second line of Balmer series obtained from is equal to that of first line of Lyman series obtained from hydrogen atom.
In the light of the above statements, choose the correct answer from the options given below :

Statement I is false but Statement II is true

Both Statement I and Statement II are true

Statement I is true but Statement II is false

Both Statement I and Statement II are false

Text Solution

Verified by Experts

The correct answer is:

Statement I: Electric discharge through causes dissociation into excited atoms which emit discrete frequencies (line spectrum). This is true.
Statement II: Using
For , second Balmer line
For H ( ), first Lyman line ( ):
Both frequencies are equal. Statement II is true.
Both statements are true.
