Question

A photon is emitted in transition from n =4 to n =1 level in hydrogen atom. The corresponding wavelength for this transition is (given, h =4 × 10-15 eVs ) : (A) 941 nm (B) 974 nm (C) 99.3 nm (D) 94.1 nm

( hc /λ)=[1-(1/16)](13.6 eV ) So, λ=94.1 nm

Q. A photon is emitted in transition from $n = 4$ to $n = 1$ level in hydrogen atom. The corresponding wavelength for this transition is (given, $h = 4 \times 1 0^{- 15} e V s$ ) :

$941 nm$

$974 nm$

$99.3 nm$

$94.1 nm$

$\frac{h c}{λ} = [1 - \frac{1}{16}] (13.6 e V)$
So, $λ = 94.1 nm$
