## What transitions occur in the Lyman series?

The first line in each series is the **transition from the next lowest number in the series to the lowest** (so in the Lyman series the first line would be from n=2 to n=1) and the second line would be from from the third lowest to the lowest (in Lyman it would be n=3 to n=1) etc etc.

## How the lines in the Lyman series are formed?

In physics and 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 n ≥ 2 to n = 1** (where n is the principal quantum number), the lowest energy level of the electron.

## What transitions correspond to the Balmer series the Lyman series the Paschen series?

The first members of the Lyman series, for instance, corresponds to the transition n = 2 → n = 1 and is referred to as Lyman-α ( ), while the first member of the Paschen series corresponds to the**transition n = 4 → n = 3**and is referred to as Paschen-α ( ).

## What is the wavelength of first transition of Lyman series?

Hence the wavelength of the first line in the Lyman series of the hydrogen spectrum is **λ=121.6nm** .

## What type of electron orbit transitions produce the ultraviolet lines in hydrogen Lyman series?

The Lyman series of lines is due to transitions from **higher-energy orbits to the lowest-energy orbit** (n = 1); these transitions release a great deal of energy, corresponding to radiation in the ultraviolet portion of the electromagnetic spectrum.

## Which spectrum of hydrogen consists of Lyman Balmer and Paschen series?

The Lyman series is in the ultraviolet while the Balmer series is in the visible and the Paschen, Brackett, Pfund, and Humphreys series are in the **infrared**.

## In which region of the spectrum does Paschen Lyman and Balmer series lie?

line spectra …for m = 1, the Lyman series, lie in the ultraviolet part of the spectrum; those for m = 2, the Balmer series, lie in the visible spectrum; and those for m = 3, the Paschen series, lie in**the infrared**.

## How are Balmer series and Paschen series originated in hydrogen spectra?

We get Balmer series of the hydrogen atom. It is obtained in the visible region. Paschen Series: **If the transition of electron takes place from any higher orbit** (principal quantum number = 4, 5, 6, …) to the third orbit (principal quantum number = 3).

Paschen series is a sequence of absorption or emission lines along the near infrared part of the hydrogen atom. This is caused by **the electron jump between the 3rd energy level and the higher levels**.

## What is Lyman series show that the frequency of the first line in the Lyman series is equal to the difference between the limiting frequency of the Lyman and Balmer series?

Answer: The ‘**series limit**‘ refers to the ‘shortest wavelength’. Here, k is a constant. Thus, the difference in the frequencies of the series of Lyman series and Balmer series is equal to the frequency of the first line of the Lyman series.

## Which of the lines in the Lyman series has the lowest energy of light explain your answer?

A For the Lyman series, n1 = 1. The lowest-energy line is due to **a transition from the n = 2 to n = 1 orbit** because they are the closest in energy.

## Which of the lines in the Lyman series has the lowest energy of light?

The lowest energy transition in the Lyman series is from **n=1 to n=2**. Hence option c is correct.

## What is last line of Lyman series?

Take the ratio of both the equation of Lyman and Balmer series and it is written as shown below. So, from the above calculation it is concluded that the ratio of wavelength of the last line of the Balmer series and the last line of the Lyman series is **4**.

## What is the first line in the Lyman series?

The first emission line in the Lyman series corresponds to **the electron dropping from n=2 to n=1** . For a positive wavelength, we set the initial as n=1 and final as n=2 for an absorption instead.

## What is the wavelength of the Lyman line in muonic hydrogen?

The wavelengths of spectral lines from the muonic atom are 207 times smaller than the wavelengths of the electronic atom. The shortest wavelength of the muonic Lyman series is **0.44 nm**, which is the X-ray part of the electromagnetic spectrum.

## Which transition between Bohr orbits corresponds to third line in Balmer series of hydrogen spectrum?

So, from the above explanation we get that the third line of the Balmer series of the hydrogen spectrum will be corresponding to **n1 =2 to n2 = 5**.

## What is the wavelength of the line in the Paschen series of hydrogen?

It is one of the hydrogen line series, such as the Lyman series and Balmer series and is named after Friedrich Paschen. Lines: **4 -> 3: 1875 nm**.

## What is the difference between Lyman and Balmer series?

The key difference between Lyman and Balmer series is that **Lyman series forms when an excited electron reaches the n=1 energy level** whereas Balmer series forms when an excited electron reaches the n=2 energy level. Some lines of blamer series are in the visible range of the electromagnetic spectrum.

## Which spectral lines may appear in both emission and absorption spectrum of hydrogen?

Seriesn1Spectral RegionLyman1**Ultraviolet****Balmer**2VisiblePaschen3InfraredBrackett4Infrared

## Why does hydrogen only have 4 spectral lines?

Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the **energy difference** of the shells causes different wavelengths to be released… hence, mono-electronic hydrogen has many spectral lines.

## What is the wavelength of the highest frequency line in the Lyman series of H spectrum?

Assertion (A):In Lyman series of H-spectra, the maximum wavelength of lines is **121.56 nm**.

## What is the transition spectrum of hydrogen?

According to the question, the desired transition for hydrogen will have the same wavelength as that of He+. **n1 = 1 and n2 = 2**. ∴ The transition for n2 = 2 to n = 1 in hydrogen spectrum would have the same wavelength as Balmer transition n = 4 to n = 2 of He+ spectrum.

## How do you explain the existence of various series of spectral lines in the hydrogen spectrum?

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**.

## What is the wavelength of third spectral line of Paschen series in hydrogen atom?

Sol. For the third member of Paschen series n = 3, n, = 6 E, -E, = 2.18×109 D or E,-E, = **2.18×10-18 = 0.1817×10-18**.

## Is Lyman series a continuous spectrum?

1 **Lyman series is a continuous spectrum**. … 3 Balmer series is a line spectrum in the ultraviolet. 4 The spectral series formula can be derived from the Rutherford model of the hydrogen atom.

## What is Lyman series Class 11?

(1) When the electron jumps from energy level higher than n=1 ie. n=2,3,4,5,6 ….to n=1 energy level, the group of lines produced is called lyman series. These lines lie in the **ultraviolet region**. … (3) Paschen series is obtained by the electronic jump from 4th, 5th or any higher energy level to 3rd energy level.

## Why do the lines in a particular series of lines get closer together at higher frequencies?

The spectrum lines become closer together the further from the nucleus. This is because **the energy levels are closer together further from the n energy levels they are**.

## What is the electron transition of a hydrogen atom?

It has one electron attached to the nucleus. The energy in a hydrogen atom depends on the energy of the electron. When the electron changes levels, it **decreases energy** and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level.

## How many spectral lines does hydrogen have?

The electron energy level diagram for the hydrogen atom. He found that the **four** visible spectral lines corresponded to transitions from higher energy levels down to the second energy level (n = 2).

## What is Series limit?

Definition of series limit : the position (as of a wavelength, wave number, or frequency) in an atomic line spectrum toward which the series progresses in the ultraviolet direction and which though there is no line at this point corresponds to **the limiting value of photon energy characteristic of the series**.
