The limiting line in Lyman series will have a frequency 6.22 x 1015 s-1 .
What is the frequency of limiting line in Balmer series?
8.22 × 1014 s−1 .
How do you find the limiting line of a Lyman series?
- For Lyman series, n1=1.
- For shortest wavelength in Lyman series (i.e., series limit), the energy difference in two states showing transition should be maximum, i.e., n2=∞.
- For longest wavelength in Lyman series (i.e., first line), the energy difference in two states showing transition should be minimum, i.e., n2=2.
What is limiting line of a series?
The limiting line is basically when you consider shoving a new electron into the atom and forcing it to land in the destination energy level nf for the particular series ... =Z2⋅5.4497×10−19J .
What is the frequency of the first line in the Lyman series?
The frequency of the first line in Lyman series in the hydrogen spectrum is γ .
What is the limiting line?
noun. A line constituting a limit or point of furthest (permitted) extent ; a cordon; a boundary; specifically a solid white line across a road indicating the point where traffic should stop (before a pedestrian crossing, etc.).

What is the wavelength of limiting line of Balmer?
Limiting line in the Balmer series has a wavelength of 364.4 nm .
What is the frequency of the red hydrogen Balmer line?
Explanation: The Balmer series corresponds to all electron transitions from a higher energy level to n=2 . where R′ is the Rydberg constant expressed in energy units ( 3.290×1015Hz ).
How do you determine the shortest wavelength of the Lyman series?
- For Lyman series, n1=1.
- For shortest wavelength in Lyman series (i.e., series limit), the energy difference in two states showing transition should be maximum, i.e., n2=∞.
- For longest wavelength in Lyman series (i.e., first line), the energy difference in two states showing transition should be minimum, i.e., n2=2.
What is the definition of limiting wavelength?
: 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.
Which of the following is are correct a limiting line of Balmer series?
The series limit is the last line in the spectrum . When $ {n_2} = infty $ , the limiting line is the one with the shortest wavelength and highest energy. Hence option d is correct.
What is the last line of Balmer series?
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 . Hence, the option (D) is correct. Note: The wavelength of the Balmer and Lyman series can be calculated using the emission spectrum expression.
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 . Reason (R): Wavelength is maximum when the transition is from the very next level.
What is the region of Lyman series?
The Lyman series lies in the ultraviolet , whereas the Paschen, Brackett, and Pfund series lie in the infrared.
What is H alpha line of Balmer series?
H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series with a wavelength of 656.28 nm in air; it occurs when a hydrogen electron falls from its third to second lowest energy level. H-alpha light is the brightest hydrogen line in the visible spectral range.
