The four spectral lines of the Balmer series that fall in the visible range are:
656.3 nm . . . . red
486.1 nm . . . . cyan
434.1 nm . . . . blue
410.2 nm . . . . violet
There are four more lines in the Balmer series ... all in the ultraviolet ... and
at least thirty-six observable lines altogether from the hydrogen atom.
No, an atomic emission spectrum is not a continuous range of colors. It consists of discrete lines of specific wavelengths corresponding to the emission of light from excited atoms when they return to lower energy levels. Each element has a unique atomic emission spectrum due to its unique arrangement of electrons.
It's a line spectrum because of the quantization of energy- meaning you only see energy with levels n=1,2,3.... One would never see the energy level n=2.8 for instance- that would be the case if it were continuous rather than a line spectrum.
The helium lamp spectrum is important in atomic emission spectroscopy because it provides a reference for identifying and calibrating the wavelengths of light emitted by other elements. By comparing the emission lines of unknown samples to the known lines of helium, scientists can determine the elemental composition of a sample.
The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.
The Lyman series refers to a series of spectral lines in the ultraviolet region of the electromagnetic spectrum that are emitted by hydrogen atoms when electrons transition to the n=1 energy level. These transitions result in the emission of photons with specific wavelengths that are characteristic of the Lyman series.
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
Niels Bohr studied the emission lines of Hydrogen.
Each colored line in hydrogen's emission spectrum corresponds to a specific transition of an electron between energy levels in the hydrogen atom. The wavelengths of these lines are unique to each transition, creating a distinct pattern that can be used to identify elements and their energy levels.
The spectrum of helium consists of distinct lines at specific wavelengths, known as emission lines, due to the transition of electrons between energy levels. In contrast, the spectrum of white light from the Sun is continuous, with all visible wavelengths present. The presence of absorption lines in the solar spectrum, caused by elements in the Sun's atmosphere absorbing specific wavelengths, further distinguishes it from the discrete emission lines of helium.

The mathematical equation that allows one to calculate the wavelengths of each line in the hydrogen emission spectrum was discovered by Danish physicist Niels Bohr in 1913 as part of his model of the hydrogen atom. This equation is known as the Balmer equation and helped to explain the spectral lines observed in hydrogen emission spectra.
The emission spectra for hydrogen and helium differ in the specific wavelengths of light they emit. Hydrogen emits light in distinct lines corresponding to transitions of its electrons between energy levels, while helium emits a continuous spectrum of light.
Helium has more emission lines than hydrogen because it has more electrons and energy levels, leading to more possible transitions between these levels and the emission of different wavelengths of light.
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
The emission spectrum of barium nitrate typically includes several bands of light in the visible region, with some lines in the blue-green part of the spectrum being the most prominent. The specific wavelengths and intensities of these lines can vary depending on the experimental conditions.
Sunlight produced spectrum is continuous and contains a broad range of wavelengths, while hydrogen gas produced spectrum consists of discrete lines at specific wavelengths due to the unique energy levels of hydrogen atoms. Sunlight spectrum is continuous due to the various processes that produce light, whereas hydrogen gas spectrum is a result of the energy levels of hydrogen atoms emitting photons of specific wavelengths.
