When an electrons comes back from fifth orbit to ground state of Hydrogen atom the total number of spectral lines and lines in UV regions are?
1)6,4
2)10,4
3)10,3
4)6,3
please help me okay? I really need it with explanation..And I promise I will follow u

Answer:
a survey was conducted by a group of students as a part of theri environment awareness programme in which they collected the following data regarding the number of plants in 20houses in a locality find the mean number of plants per house in step deviation method

Answer:
Number of visible lines when an electron returns from 5th orbit to the ground state in the H spectrum is 10.
The number of spectral lines =
2
n(n−1)
.
The number of spectral lines =
2
5(5−1)
=10.
These lines belong to the UV region.
Note: Lyman series corresponds to transitions to n=1 level.
So, the correct option is D
