Question

Ex of Rydberg Equation wow (fer sH I HM E.00 Calculate the wavelength (in nm) of the line in the hydrogen atom spectrum, for which nA = 2 , nB = 3. 20100.8 = (3.00)

Answer 1

Rydberg equation determine wame length peocess of de-excitation or of emitted excitation photons in the av higher En energy for higher enerzy shell - Lower energy shell level } for levels En En na ne += R 22 h nd e Rydberg equation. - equation dy Wanelength Rt Rydberg Constant C R = 272 miley CH3 R = 109700 Curl R = 10097 x 107 mil I = 9.2 nm or 912 A can be equation d= 1 Raf further simplified ) d = 91.2 mm z link hoe n3 1 Z= atomic number of the atom 11. — 400 ей 09 я едло! MBT higher energy level,

For given Hydrogen that atom n=2 z=1 NB=3 a = 91.2 nm 22 IL - II In ☆ me 2 = 91.2 nm Ko ies] calculation d = 91. arm 1-1 = 4 9 9-4 36 =) 5 = 36 0.1389 - 91.2 nm 0.1389 = 656.58 nm
