The ratio of minimum to maximum wavelengths in Balmer series of $H$ -atom is

Options:

Answer:

Solution:

We know that

$\frac{1}{λ_{m i n}} = R (\frac{1}{4} - \frac{1}{\infty}) = \frac{R}{4}$

$\frac{1}{λ_{m a x}} = R (\frac{1}{4} - \frac{1}{9}) = \frac{5 R}{36} \Rightarrow \frac{λ_{m i n}}{λ_{m a x}} = \frac{\frac{4}{R}}{\frac{36}{5 R}} = \frac{5}{9}$
