Why do stars of spectral class M not show strong lines of hydrogen in their spectra?
Stars of spectral class M have cooler temperatures compared to stars of other spectral classes, causing their hydrogen lines to weaken and be less prominent in their spectra. The lower temperature results in lower energy levels, making it more difficult for hydrogen atoms to transition between energy levels and emit or absorb light in the hydrogen spectral lines.
Which element produce the largest number of lines?
Hydrogen produces the largest number of spectral lines due to its simple atomic structure.
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
What is beryllium spectral lines?
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
Quasars have what kind of spectral lines?
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.

Why can't a single atom of hydrogen produce all four hydrogen spectral lines simultaneously?
A single atom of hydrogen cannot produce all four hydrogen spectral lines simultaneously because each spectral line corresponds to a specific energy transition within the atom's electron configuration. Due to the laws of quantum mechanics, an atom can only emit or absorb energy in discrete amounts, leading to the emission of specific spectral lines corresponding to specific energy transitions.
How did scientist discovered that stars were made up mostly of hydrogen since stars are so far away rom earth?
Scientists studied the light emitted by stars and found that the spectral lines corresponded to those of hydrogen. By analyzing these spectral lines through spectroscopy, scientists were able to identify the elements present in stars, with hydrogen being the most abundant element. This discovery revolutionized our understanding of the composition of stars and the universe as a whole.
Which element produce the largest number of lines?
Hydrogen produces the largest number of spectral lines due to its simple atomic structure.
How can elements with low atomic number (like Hydrogen) have so many spectral lines?
Elements with low atomic number can have many spectral lines because their electrons can transition between different energy levels in multiple ways. These transitions result in the emission or absorption of photons with different wavelengths, leading to a variety of spectral lines in the electromagnetic spectrum. In the case of hydrogen, the simple structure of its atom allows for many possible energy level transitions, giving rise to a rich spectrum of spectral lines.
When astronomers look for evidence of hydrogen gas in the spectra of the Sun the planets and nearby stars the positions of the spectral features or lines due to hydrogen are different or the same?
They are the same.
What led niels bohr to his discover?
Bohr proposed his model for the atom because (1) it easily explained spectral lines of hydrogen and (2) other models failed to do so. The model was accepted when it was successful in predicted spectral lines of ionized helium.
What is the shortest wavelength present in brackett series of spectral lines?
The shortest wavelength present in the Brackett series of spectral lines is in the infrared region around 1.46 micrometers. This series represents transitions in hydrogen atoms from higher energy levels to the n=4 energy level.
The spectral lines from distant galaxies do not match spectral lines on Earth due to?
The spectral lines from distant galaxies do not match those on Earth because of the Doppler effect, cosmic expansion, and differences in elements present in the galaxies. These factors cause the observed spectral lines to be shifted or altered compared to what we see on Earth.
In science what is meant by the Lyman series?
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.
What is the splitting of spectral lines called?
Spectroscopy.
What is beryllium spectral lines?
Beryllium spectral lines are specific wavelengths of light emitted or absorbed by beryllium atoms when they undergo transitions between energy levels. These spectral lines are unique to beryllium and can be used in spectroscopic analysis to identify the presence of beryllium in a sample.
