Question

Calculate longest wavelength in astroms in Balmer series in single lonised

Answer 1

Answer:

Longest wavelength is emitted in Balmer series if the transition of electron takes place from n2=3 to n1=2.

∴ Longest wavelength in Balmer series λL1=R(221−321)

Or λs=5R36

⟹ λs=5×1.097×10736=656.3nm

Answer 2

Answer:

Longest wavelength is emitted in Balmer series if the transition of electron takes place from n2=3 to n1=2.

∴ Longest wavelength in Balmer series λL1=R(221−321)

Or λs=5R36

⟹ λs=5×1.097×10736=656.3nm
