# FAQ: What Is The Longest-Wavelength Line In Nanometers In The Infrared Series For Hydrogen Where?

What are the two longest-wavelength lines in nanometers in the series of the hydrogen spectrum when m = 1 and n 1? The wavelength λ is greatest when n is smallest; that is, when n = 2 and n = 3. or The two longest-wavelength lines are at 121.5 nm and 102.6 nm.

## What is the longest wavelength of light emitted by hydrogen?

When an electron drops from energy level 3 to energy level 2, red light is emitted. The red light has the longest wavelength, lowest energy, and lowest frequency.

## What is the longest wavelength in NM?

The longest wavelength corresponds to the smallest energy difference between energy levels, which in this case will be between n = 2 and n = 3. ⇒ λ = 6.56 × 10-7 m = 656 nm. Thus the longest wavelength in the Balmer series is 656 nm.

## What will be the longest wavelength line in the series of spectrum?

Since wavelength and energy are inversely related, the longest wavelength would be produced by the lowest amount of energy. That would be by the electron falling from from n = 3 (ni) to n = 2 (nf). (All Balmer series lines have nf = 2). lambda = 1 / (1.52 x 10^6 m) = 6.56 x 10^-7 m = 656 nm…that’s a RED line.

## What is the longest wavelength emitted?

The longest-wavelength light that causes an electron to be emitted from gaseous lithium atom is 520 nm.

## What is the longest wavelength in nm in the Paschen series of atomic spectra?

The atom can also be induced to jump to a higher energy level. One way to accomplish this is to strike the atom with a photon. This requires the photon to have precisely the energy difference from one atomic level to another. The wavelength of the series limit of the Paschen series is 820.1 nm.

## What is the longest wavelength in the Paschen series of atomic spectra?

Therefore, the longest wavelength that can be achieved in Paschen’s series is 1875 angstroms.

## What is the longest wavelength of Lyman series?

What is the longest wavelength of Lyman series? So, the longest wavelength is 1.22×10−5cm. Therefore, the shortest and longest wavelengths in hydrogen spectrum of Lyman series are 9.11×10−6cmand 1.22×10−5cm respectively.

656nm.

## What is the longest wavelength line in the Lyman series of H ion?

Explanation: Just put value of 1/RH = 912 Angstroms to get value of maximum wavelength.

## Which transition in the hydrogen atom has the longest wavelength?

Based on the obtained values, the transition that represents the emission of the longest wavelength photon is n = 5 to n = 4 (i.e., 4050 nm).
