Question

a beam of electron bombards a sample of hydrogen .through potential difference must electron have been accelerated if the first line "paschen" series is to be emitted.a beam of electron bombards a sample of hydrogen .through potential difference must electron have been accelerated if the first line "paschen" series is to be emitted.

Answer 1

Answer:

accelerated" (and any subsequent words) was ignored because we limit queries to 32 words.

Answer 2

The highest state that can be achieved the the electron is:

Energy attained =Ve

E=12.75 eV

12.75=13.6(1−

⇒n=4

So, the electron gets excited to n=4.

It can come back to n=3, n=2, n=1

Paschen, Blamer, and Lymen series
