What is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? For example, if a spectrometer with a wavelength range of 200nm had a spectral resolution of 1nm, the system would be capable of resolving a maximum of 200 individual wavelengths (peaks) across a spectr… @Gert - My explanation is a simple one. 4.7k SHARES. Suppose a beam of white light (which consists of photons of all visible wavelengths) shines through a gas of atomic hydrogen. Because a sample of hydrogen contains a large number of atoms, the intensity of the various lines in a line spectrum depends on the number of atoms in each excited state. 4.7k VIEWS. Foot note 1: Total number of spectral lines for single atom where $n_2=7$ should be: $1 \times 6 = (n_2-n_1)$ in the spectrum, not $n_1(n_2-n_1)$ as I originally suggested (Thanks @porphyrin for careful reading). Hydrogen atom in ground state is excited by a monochromatic radiation of λ = 975 A. So, maximum number of spectral lines emitted by a hydrogen atom when it is in the third excited state (n2=4) are 6. s&=6+5+4+3+2+1=21=\frac{42}{2}=\frac{7\times6}{2}\\ Making statements based on opinion; back them up with references or personal experience.

In case of single isolated atom if electron makes transition from nth state to the ground state then maximum number of spectral lines observed $ = ( n — 1)$. Two years back my friend told me a simple formula for calculating the number of spectral lines. If you have a system with $N$ energy levels and you are at level $N$, then you have only $N-1$ decay transitions. If you assume the energy levels of an atom to be a staircase; if you roll a ball down the stairs the ball only has a few "steps" that it can stop on. Number of spectral lines from a state n to ground state is : [n(n - 1) ] / 2 . 4 Calculate the wavelength of the 4 → 1 transition.

Colleagues don't congratulate me or cheer me on, when I do good work? The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula.These observed spectral lines are due to the electron making transitions between two energy levels in an atom. Can anyone explain how the process of emission differs in these two cases?

One of the most important characteristics of a spectrometer is the spectral (or optical) resolution. When acquiring a spectrum of an astronomical object, astronomers rely upon spectral lines to determine a myriad of physical properties, such as composition, temperature, ionization state, velocity, redshift and more. NOTE- I know how the formula for latter came. The electron can make a transition from . Solution for Hydrogen atoms are excited by a laser to the ?=4 state and then allowed to emit. How to stop writing from deteriorating mid-writing? Such calculations rely on very detailed knowledge of every single spectral line, usually taken from the HITRAN database [ 42 , 45 ]. What does Brightness/ intensity of spectral lines depend on? It only takes a minute to sign up. Spectral line series, any of the related sequences of wavelengths characterizing the light and other electromagnetic radiation emitted by energized atoms.
