Explain Balmer series and gives its equation.

Explanation

Balmer showed in 1885 on the basis of experimental observations that if spectral lines then the visible lines of the hydrogen spectrum obey the following formula :
`vec( v) = 109677 (1)/(2^(2)) - (1)/( n^(2))cm^(-1) `
The series of line described by this formula are called the Balmer series. They Balmer series of hydrogen spectrum which apear i n the visible region of the electromagnetic spectrum
