For minimum wavelength n2=∞, n1=n So, λ min =(n2/R)=(1/107) =1000 mathringA

Q. The shortest wavelength which can be obtained in hydrogen spectrum is $(R = 1 0^{7} m^{- 1})$

$1000 \overset{˚}{A}$

$800 \overset{˚}{A}$

$1300 \overset{˚}{A}$

$2100 \overset{˚}{A}$

For minimum wavelength $n_{2} = \infty, n_{1} = n$
So, $λ_{m i n} = \frac{n ^{2}}{R} = \frac{1}{1 0 ^{7}}$
$= 1000 \overset{˚}{A}$
