Which electron transition would correspond to the shortest wavelength line in emission spectrum of the hydrogen atom?
This means that the transition that gives the shortest wavelength has the largest frequency, energy, and distance. Choice A,
n = 6 to n = 2
, will produce the shortest wavelength since the distance between the energy levels is the greatest.
What transition causes the shortest wavelength?
Longest wavelength goes with lowest energy: Thus transition between n = 1 and n = 2 corresponds to the longest wavelength. Likewise,
the transition between n = 1 and n = 4 (highest energy)
corresponds to the shortest wavelength.

- The speed of light is constant in space. …
- A wavelength of light is defined similarly to that of water waves—distance between crests or between troughs.
Which electron transition between the energy levels of hydrogen causes the emission of a photon of visible light?
The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
When the electron changes from n=3 or above to n=2
, the photons emitted fall in the Visible Light region of the spectra.
Which electron transition corresponds to the absorption of a photon with the shortest wavelength?
From the explanation in part a),
the transition from 1 to 3
corresponds to the absorption of the photon with the shortest wavelength.
How do you find the absorption line?
Absorption lines are usually seen as dark lines, or lines of reduced intensity, on a continuous spectrum. This is seen in the
spectra of stars
, where gas (mostly hydrogen) in the outer layers of the star absorbs some of the light from the underlying thermal blackbody spectrum.
Which transition corresponds to an absorption with the highest energy?
The transition that represents absorption of a photon with the highest frequency is
n = 1 → n = 3
.
Which transition emits light with the highest energy?
The transition with the greatest distance is
5p → 1s
, which is n = 5 going to n = 1. This means this transition also has the largest energy and frequency. The answer is d. 5p → 1s.
What is the wavelength of the N 4 to N 2 transition in hydrogen?
Electron Transition Energy (J) Wavelength (nm) | Balmer Series (to n=2) | n=3 to n=2 3.03 x 10 – 19 656 | n=4 to n=2 4.09 x 10 – 19 486 | n=5 to n=2 4.58 x 10 – 19 434 |

Which of the following transitions in the hydrogen atom emits the least energy?
Complete answer:
Thus, lower the energy of emission lower would be the frequency of the photon. The lowest energy is for
n=4 to n=3 transition
.
Which transition produces a photon with the highest frequency?
Answer and Explanation: The higher the frequency a photon has, the more energy it has. Therefore
the electron transition that corresponds to
the greatest energy change will have the highest frequency.
Which of the following is of shortest wavelength?
Ultraviolet
has the shortest wavelength among the given options. Gamma rays have the shortest wavelength and highest energy in the electromagnetic spectrum.
Which of the following has the shortest wavelength quizlet?
The electromagnetic radiation that has the shortest wavelength is
gamma ray
and radio waves have the longest wavelength.
Do shorter wavelengths have higher frequencies?
Wavelength and frequency are inversely related so that longer waves have lower frequencies, and
shorter waves have higher frequencies
.
Which electromagnetic wave has the shortest wavelength and highest frequency?
Gamma rays
have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.
Do shorter wavelengths have more energy?
Light waves with shorter wavelengths (and higher frequencies) also
have more energy
, so types of light like gamma rays, X-rays, and ultraviolet light are more energetic than visible light, and infrared, microwaves, and radio waves are less energetic than the light in the visible spectrum.
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.
How do electrons transition between energy levels?
Electrons in atoms and molecules can change (make transitions in) energy levels
by emitting or absorbing a photon (of electromagnetic radiation)
, whose energy must be exactly equal to the energy difference between the two levels.
What is the smallest packet of electromagnetic energy that can be absorbed or emitted?
photon, also
called light quantum, minute energy packet of electromagnetic radiation. The concept originated (1905) in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light.
In which transition is a Balmer series photon absorbed?
∴ In
transition (VI)
, photon of Balmer series is absorbed.
Which transition corresponds to the emission of radiation of maximum wavelength justify your answer?
(i)
Transition A, for which the energy emission is minimum
, corresponds to the emission of radiation of maximum wavelength.
What occurs as the wavelength of a photon increases?
All photons travel at the speed of light. … From this equation, it is clear that the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. Thus as
frequency increases
(with a corresponding decrease in wavelength), the photon energy increases and visa versa.
How spectral lines are formed?
Spectral lines are produced
by transitions of electrons within atoms or ions
. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed….
What is the wavelength of a photon emitted during a transition from n 5 to n 2 in hydrogen atom *?
434 nm
.
What is the wavelength of a photon emitted during transition from n 4 to n 1 in the hydrogen atom?
=4.34×10−7m or
434 nm
.
What causes an absorption line?
An absorption line occurs when
an electron jumps from a lower energy state to a higher energy state
, extracting the required photon from an outside source of energy such as the continuous spectrum of a hot, glowing object.
How are absorption lines formed?
An absorption line is produced
when a photon of just the right energy is absorbed by an atom, kicking an electron to a higher energy orbit
. The photon had energy = the difference in energy of the energy orbits. … Therefore, the pattern of absorption lines is the same as the pattern of emission lines.
Is energy emitted or absorbed from n 4 to n 2?
1. A photon is emitted as an atom makes a transition from n = 4 to n = 2 level.
Which transition depicts the absorption line with the longest wavelength?
Ernest Z. The absorption with longest wavelength is
n=7→n=8
.
Why is a shorter wavelength of light emitted?
The greater the energy difference results in an emitted photon of greater energy
and therefore shorter wavelength.
Which electron transition produces light with the longer wavelength?
Because the 3p to 1s has more energy it has a shorter wavelength. The
2p – 1s

Which wavelength of light has the highest frequency?
Violet
