Chemistry - Atomic Structure Question with Solution | TestHub

The Lyman series lies in the ultraviolet, in chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from $\mathrm{n}\ge 2$to $\mathrm{n}=1$  (where $\mathrm{n}$ is the principal quantum number), the lowest energy level of the electron.

All of the wavelengths in the Balmer series are in the visible region of the electromagnetic spectrum ($400 \mathrm{nm}$ to $740 \mathrm{nm}$). The presence of Hydrogen is detected in astronomy by using the $\mathrm{H}-$Alpha line of the Balmer series; it is also a component of the solar spectrum.

All the wavelength of the Paschen series falls in the Infrared region of the electromagnetic spectrum.

Pfund series lie in the infrared.

A – II, B – IV, C – III, D – I
