바닥상태 Li^2+ 이온을 n = 2로 필요한 빛의 파장(nm)
바닥상태 Li^2+ 이온을
n = 2 준위로 들뜨게 하는데 필요한 빛의 파장(nm)
Find the wavelength of radiation required to excite an electron
in the ground level of Li^2+ (Z = 3) to n = 2 energy level.
---------------------------------------------------
Rydberg constant, R_H = 1.097×10^7 /m
1/λ = R_H Z^2 (1/n_i^2 – 1/n_f^2)
( 참고 https://ywpop.tistory.com/14147 )
= (1.097×10^7 /m) (3^2) (1/1^2 – 1/2^2)
= 7.40475×10^7 /m
λ = 1 / (7.40475×10^7 /m)
= 1.3505×10^(-8) m
(1.3505×10^(-8) m) (10^9 nm / 1 m)
= (1.3505×10^(-8)) (10^9)
= 13.5 nm
답: 13.5 nm
