1.	A hydrogen atom in an excited state emits a photon which has the longest wavelength of the Paschen series. Further emissions from the atom cannot include the
Answer» longest wavelength of the Lyman series second longest wavelength of the Lyman series longest wavelength of the Balmer series second longest wavelength of the Balmer series Solution :ELECTRON is in `3^(RD)`orbit. It may deecite to `3 to 2 , 2 to 1 , 3 to 1 ` . Therefore , the electron isin `3^(rd)` orbit. It may de-excite LIKE `3 to 2 , 2 to 1 , 3 to 1 `.Thus the other transitions do not INCLUDE `4 to 2 `
