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.
Which series of lines of the hydrogen spectrum lies in the visible region?
Only
the Balmer series
lies in the visible region.
Which are correct statements about the emission spectrum of hydrogen in the visible region?
Which statement is correct for the emission spectrum of the hydrogen atom?
The lines are produced when electrons move from lower to higher energy levels
. The lines in the visible region involve electron transitions into the energy level closest to the nucleus.
Why are only 4 lines seen in the hydrogen emission spectrum?
This is explained in the Bohr model by the realization that the electron orbits are not equally spaced. … The electron energy level diagram for the hydrogen atom. He found that the four visible spectral lines corresponded
to transitions from higher energy levels down to the second energy level (n = 2)
.
What is the emission of hydrogen?
Emission Spectrum of Hydrogen. When an electric current is passed through a glass tube that contains hydrogen gas at low pressure the tube gives
off blue light
. When this light is passed through a prism (as shown in the figure below), four narrow bands of bright light are observed against a black background.
What is the longest wavelength of Lyman series?
- 121.6 nm. …
- 182.4 nm. …
- 243.4 nm. …
- 364.8 nm. …
- Water flows steadily through a horizontal pipe of a variable cross section. …
- Which of the following statements is true?
What is the region of Lyman series?
Additional Information: Lyman series lies in
UV region
, Balmer series lies in visible light, Paschen series lies in infrared region, Brackett series lies in infrared region and Humphry series lies in far infrared region.
What is the wrong about atomic emission spectrum of hydrogen?
It is
discontinued spectrum
It is a dark line spectrum It is a bright line spectrum It is obtained by passing heat or electricity through hydrogen gas It is also called finger print of atom If you use something like a prism or diffraction grating to separate out the light, for hydrogen, you don’t get a continuous …
What is wrong about atomic emission spectrum of hydrogen Toppr?
What is wrong about atomic emission spectrum of hydrogen 1)
it is discontinuous spectrum
. … 3)it is bright line spectrum. 4)it is obtained by passing heat or electricity through hydrogen gas. 5)it is also called fingerprint of an atom.
What does the atomic emission spectrum of hydrogen look like?
A hydrogen discharge tube is a slim tube containing hydrogen gas at low pressure with an electrode at each end. If a high voltage (5000 volts) is applied, the tube lights up with a
bright pink glow
.
Why do hydrogen atoms have line spectrum?
Lines in the spectrum were
due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius
. The orbit closest to the nucleus represented the ground state of the atom and was most stable; orbits farther away were higher-energy excited states.
What is Balmer line?
The Balmer series
of atomic hydrogen
. These lines are emitted when the electron in the hydrogen atom transitions from the n = 3 or greater orbital down to the n = 2 orbital. … The electron travels in circular orbits around the nucleus. The orbits have quantized sizes and energies.
What is meant by hydrogen spectrum?
The hydrogen spectrum is an important piece of evidence to show the quantized electronic structure of an atom. … It
results in the emission of electromagnetic radiation initiated by the energetically excited hydrogen atoms
. The hydrogen emission spectrum comprises radiation of discrete frequencies.
