Which of the following statement(s) is(are) correct about the spectrum of hydrogen atom?

The ratio of the longest wavelength to the shortest wavelength in Balmer series is $$\frac{9}{5}$$

There is an overlap between the wavelength ranges of Balmer and Paschen series

The wavelengths of Lyman series are given by $$\left(1 + \frac{1}{m^2}\right)\lambda_0$$, where $$\lambda_0$$ is the shortest wavelength of Lyman series and m is an integer

The wavelength ranges of Lyman and Balmer series do not overlap
