A sample of hydrogen is bombarded by electrons. Through what potential difference should the electrons be accelerated so that third line of Lyman series be emitted?

A

`2.55 V`

B

`10.2 V`

C

`12.09 V`

D

`12.75 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`13.6 - 0.85 = 12.75 eV`
So, `12.75 V` in the required potential difference.
