| 587.5618 nm | yellow | helium |
| 589.2938 nm | orange | sodium |
What is the wavelength of the spectral line?
A typical spectral line in the visible region of the spectrum has a wavelength of 5.8 × 10−5 cm; this wavelength corresponds to a frequency (ν) of 5.17 × 1014 Hz (hertz equals one cycle per second) obtained from the equation.
What are the wavelengths produced by hydrogen?
The visible spectrum of light from hydrogen displays four wavelengths, 410 nm, 434 nm, 486 nm, and 656 nm, that correspond to emissions of photons by electrons in excited states transitioning to the quantum level described by the principal quantum number n equals 2.
What is the emission wavelength of mercury UV lamp?
In medium-pressure mercury-vapor lamps, the lines from 200–600 nm are present. The lamps can be constructed to emit primarily in the UV-A (around 400 nm) or UV-C (around 250 nm)….Emission line spectrum.

What are the wavelengths of the major lines in the line spectrum of neon?
Question: The most prominent line in the emission spectrum of neon is found at 865.438 nm. Other lines are located at 834.761 nm, 878.062 nm, and 885.387 nm.
Why is mercury in fluorescent light bulbs?
Mercury is an essential element in the operation of fluorescent lighting; it allows the bulbs to be an efficient light source. Because CFLs contain trace amounts of mercury, it is important to educate yourself on proper use, recycling and disposal of these products.
What is the wavelength of the spectral line corresponding to the highest energy transition in the visible region of hydrogen spectrum?
The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm.
Which transition in the hydrogen atom emits visible light?
Balmer series lines
The visible photons in the hydrogen spectrum are the Balmer series lines. The lowest energy and longest wavelength photon corresponds to the 3→2 transition and is red.
