The first line of the Lyman series is the transition when an electron drops from n=2 to n=1 in a hydrogen atom, producing a photon with wavelength 121.6 nm.
What is second line of Lyman series?
The second line of the Lyman series corresponds to the electron transition from n=3 to n=1.
To find its wavelength, we use the Rydberg formula: 1/λ = R(1/1² − 1/3²) = 8R/9, which gives λ = 9/(8R). You'll find this line just to the left of the first line in the ultraviolet spectrum. Honestly, this is the most straightforward calculation in hydrogen spectral series.
What is the value of first line of Lyman series?
The first line of the Lyman series has a wavelength of 121.6 nm (or 1216 Å).
Here's how we get that number: it comes from electrons dropping from the first excited state (n=2) to the ground state (n=1). The Rydberg constant R is about 1.097×10⁷ m⁻¹, and the calculation uses λ = 4/(3R). Now, that's a clean formula you can trust.

What is first line of Balmer series?
The first line of the Balmer series is the H-alpha line, produced by the electron transition from n=3 to n=2.
This transition gives off a red photon at 656 nm. Unlike the Lyman series, the Balmer lines sit in the visible spectrum, which is why you can actually see them in lab demonstrations. That makes them perfect for teaching spectroscopy.
What is the wavelength of 1st line of Lyman series?
The wavelength of the first line of the Lyman series is 121.6 nm.
In most lab settings, people round this to 122 nm for simplicity. It's deep in the ultraviolet, so you won't see it with your eyes. The series limit, where all lines converge, sits at 91.2 nm—shorter than any Balmer line could ever be. If you're planning your first trip to Italy and want to explore scientific landmarks, consider visiting historical sites related to physics.
What is the value of R in Lyman series?
The Rydberg constant R for the Lyman series is approximately 10,973,731.56816 per meter.
This constant sets the spacing between all hydrogen spectral lines. Multiply it by the speed of light, and you get the frequency of the emitted photon. For wavelength calculations, we usually keep R in units of m⁻¹—it's the most practical way to use it.

What is the last line of Lyman series?
The last line of the Lyman series is the series limit, occurring at a wavenumber of 109,677 cm⁻¹.
This limit happens when electrons fall from an infinitely high energy level straight down to n=1. The corresponding wavelength is 91.2 nm, which is the shortest possible in the series. After this point, no more discrete lines appear. For those considering career paths in fitness, you might explore online personal trainer certifications.
What is the shortest wavelength of Lyman series?
The shortest wavelength in the Lyman series is 91.2 nm.
This is the famous Lyman limit. As initial energy levels get higher and higher, the lines get closer together until they merge at this point. No discrete transitions exist beyond 91.2 nm in this series.
What is last line of Balmer series?
The last (series limit) line of the Balmer series occurs at a wavelength of 364.6 nm.
This marks the transition where electrons fall from n=∞ to n=2. The Balmer series limit sits right at the edge of visible and ultraviolet light—just where things get tricky to observe. If you're exploring career options, understanding the triple bottom line can provide valuable insights.
What is the wave number of 2nd line in Lyman series?
The wavenumber of the second line in the Lyman series is 8R/9.
This comes directly from the Rydberg formula for the n=3 to n=1 transition. Wavenumber tells us how many waves fit in a given length, and it's directly tied to photon energy. That's why this value matters so much in spectroscopy.
What is the difference between Lyman Balmer and Paschen series?
The Lyman series involves transitions to n=1, the Balmer series to n=2, and the Paschen series to n=3.
Each series lands in a different part of the spectrum: Lyman in UV, Balmer in visible, Paschen in infrared. The energy gaps shrink as the lower level number goes up. That's why the Paschen lines are less energetic than Balmer's. For a deeper dive into historical discoveries, read about the first inventions in medicine.
What is the wavelength of first line of Balmer series?
The wavelength of the first line of the Balmer series is 656 nm.
That's the H-alpha line, a deep red color astronomers love. You can spot it in hydrogen discharge tubes, and it's crucial for studying hydrogen in stars. No wonder it's the most famous line in astronomy.
What is the Balmer series limit?
The Balmer series limit is at 364.6 nm.
This is where all Balmer lines converge as initial energy levels approach infinity. Beyond this point, you won't find any more discrete Balmer lines—just a smooth continuum.
What is the range of Lyman series?
The Lyman series spans wavelengths from 121.6 nm down to 91.2 nm.
All these lines sit in the ultraviolet, completely invisible to human eyes. The series starts at 121.6 nm and converges toward 91.2 nm. That's the full extent of the Lyman range.
What is the region of Lyman series?
The Lyman series lies entirely in the ultraviolet region of the electromagnetic spectrum.
Compare that to Balmer (visible) or Paschen (infrared), and you see why Lyman lines need special equipment. Ultraviolet observations aren't something you can do with a standard spectroscope. If you're considering online roleplaying communities, read our article on whether online roleplaying constitutes cheating.
How is Balmer series produced?
The Balmer series is produced by electron transitions within the second energy level (n=2) of the hydrogen atom.
Electrons from higher states (n≥3) drop to n=2, releasing visible photons. The H-alpha line at 656 nm gives that characteristic red glow in hydrogen tubes. That's how you get those beautiful red spectra in physics labs.
