When the wavelength of spectral lines emitted from an object decreases which end of the visible light spectrum does it move toward and what is the objects motion relative to earth?
When the wavelength of spectral lines emitted from an object decreases, it moves towards the violet end of the visible light spectrum. This is known as a blueshift, indicating that the object emitting the light is moving towards Earth.
When the wavelengths of spectral lines emitted from an object decreases with end of the visible light spectrum as it moves toward?
When the wavelengths of spectral lines emitted from an object decrease toward the end of the visible light spectrum, it indicates that the object is moving toward the observer, a phenomenon known as the blue shift. This occurs due to the Doppler effect, where the frequency of light waves increases as the source approaches the observer. Consequently, the emitted light shifts toward shorter wavelengths, which can provide information about the object's velocity and motion in space.
Which term refers to the energy emitted when an electron moves from a higher energy level to a lower one?
neutron
When the wavelength of spectral emitted from an objectincreases which end of the visiblelight spectrum does ti move toward and what is the objects motion relative to earth?
When the wavelength of spectral light emitted from an object increases, it moves towards the red end of the visible light spectrum, also known as the redshift. This indicates that the object is moving away from Earth.
Is energy emitted or absorbed when an electron moves from an excited state to a ground state?
Emitted, and the precise amount of energy that is emitted will depend on what kind of atom, and moving from which excited state. That's how spectrographs can determine what element is present.
Is energy absorbed when an electron moves to a closer shell?
No, energy is released when an electron moves to a closer shell. This process is known as an electron transition or recombination, and it typically results in the emission of light or other forms of electromagnetic radiation. The energy difference between the two shells is released in the form of a photon.
When one electron moves from the 4th shell to the 2nd shell in hydrogen is energy absorbed or emitted by the atom?
The energy is absorbed by the electrons because work needs to be done on the electrons to raise them to an excited state. Energy is stored in the electrons while they are in their excited state and would emit energy if they returned to their ground state.
According to Bohr's model of the hydrogen atom how is hydrogen's emission spectrum produced?
In Bohr's model of the hydrogen atom, hydrogen's emission spectrum is produced when electrons jump between different energy levels within the atom. When an electron moves from a higher energy level to a lower one, it releases energy in the form of light, which is observed as distinct spectral lines in the emission spectrum. The energy of the emitted light corresponds to the energy difference between the initial and final energy levels of the electron.
What causes the emission of radiant energy that produces characteristics spectral lines?
The emission of radiant energy that produces characteristic spectral lines is caused by electrons in atoms transitioning between energy levels. When an electron moves from a higher energy level to a lower one, it releases energy in the form of photons. Each element has a unique set of energy levels, resulting in distinct spectral lines that can be used for identification.
The more spectral lines of a star are shifted to the red end of the spectrum the?
The more spectral lines of a star are shifted to the red end of the spectrum, the more it indicates that the star is moving away from us. This phenomenon is known as redshift, and it is a result of the Doppler effect caused by the expansion of the universe.
When the wavelength of the spectral line emitted from an object decreases which end of the visible light spectrum does it move toward and what is the object's motion relative to Earth?
If the wavelength decreases, the spectral line moves towards the blue end of the visible light spectrum. This phenomenon is known as blue shift, indicating that the object is moving towards Earth.
When the wavelength of a spectral line emitted from an object decreases which end of the visible light spectrum does it move toward and what is the object and motion relative to Earth?
When the wavelength of a spectral line emitted from an object decreases, it moves toward the blue end of the visible light spectrum. This phenomenon indicates that the object is moving toward Earth, a scenario known as blue shift. Common examples include distant galaxies or stars that are moving closer to us.
