frequency is proporrional to the z^2/n^3

where z is the atomic nuber and n is the quantum number respectively.

Vn = k*(z^2/n^3)...................(1)

V1 = k*(z^2)...........................(2)

Dividing both eqns. we get,

Vn/V1 = 1/n^3

Taking log both sides we get,

log(Vn/V1) = -3log(n)

It can be written in a stratight line between log n and log (Vn/V1) as =>

x = -3y

y = -x/3 which is a straaight line with negative slope and intercept zero which means it will pass thorugh origin.
