Question

The electronic transitions for n = 2 to n = 1 will produce shortest wavelength in (where n = principle quantum state)​

Answer 1

Answer:

Hydrogen atom.

Explaination:-

In hydrogen atom

1/¥ = R[1/n1^2-1/n2^2]

So transition from n= 2 to n=1 will produce shortest wavelength.

EXPLANATION —

Since we know

$\frac{1}{λ} = R( \frac{1}{ {n1}^{2} } - \frac{1}{ {n2}^{2} } ) {Z}^{2}$

=> 1/λ= R ( 1/1² - 1/2²) Z²

=> 1/λ = 3/4 RZ²

Here λ is invertionly proportional to Z²

Therefore, For shortest λ, Z must be maximum which is for Hydrogen
