Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?

The shorter the wave length the more energy. The further the electron falls, the more energy that will be emitted and the shorter the wavelength.

Whenever an excited hydrogen atom falls back from an excited state to its ground state it?
The answer is (B) Emits a Photon of Radiation.
How is light produced when elements are heated to high temperatures?
This is particularly true to metals, and are the basis for flame tests and even for flame AAS analysis. When a metal is heated, the energy is taken in, and this promotes an electron to the lowest unoccupied molecular orbital (LUMO). When this electron falls back down to the highest occupied molecular orbital (HOMO) the energy is often released as light, with a wavelength proportional to the energy difference between the HOMO and LUMO.
What types of electromagnetic radiation can be released when an electron falls from an excited state to a ground state?
Whenever the electron falls from an excited state to a lower level, energy is released in the form of electromagnetic radiation. The Electromagnetic radiation can be light of different wavelengths and therefore different colors
Explain how the wavelengths of light emitted by an atom provide information about electron energy levels?
We know what a wavelength is, and when we apply the term to the phenomenon of electron energy levels, something amazing happens. Let's review by looking at atomic structure for a moment and take off from there. We know that electrons form up in orbitals and shells around an atomic nucleus. These orbitals are defined as energy levels, and an electron is said to be in a given energy level. When electrons get just the right amount of energy, they can "jump" to a higher energy level. There are places that they cannot go, but there are other places that are "just right" for an electron from that particular starting energy level. A specific quantity of energy (a quantum, perhaps) is the key to electrons changing energy levels. If an electron is "bumped" to a higher energy level because it has "accepted" a packet of energy that is just right, it moves up to that energy level. But it cannot stay there, so it "falls back" to where it came from. In returning to its original energy level, it must "give up" the exact amount of energy that it took to move up. This specific amount of energy translates into radiated electromagnetic energy of a given wavelength or frequency. And each wavelength corresponds to a given amount of energy. Let's apply this and see what happens. Should we consider a bunch of atoms of a given kind, they will have a specific electron structure. The electrons of these atoms "live" in given energy levels. If we excite these atoms with the right amounts or quanta of energy, the electrons that will only respond to that amount of energy will move to a higher energy level. Then the electrons will return to their original levels, giving up that wavelength of energy when they drop down. If the wavelength of electromagnetic energy is in the optical band, visible light will appear. The atoms will "glow" at a specific color associated with the wavelength of the energy that is released when those electrons return to their original energy levels. If those atoms in our experiment are a gas and we apply sufficient voltage, the gas atoms will ionize and the gas will glow. Electrons are accepting energy quanta, are moving to higher energy levels, and are then returning to their original energy levels by releasing visible light of a given color. Electron energy levels are directly related to wavelengths of electromagnetic radiation.
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
This energy is released as a photon.
Why is a shorter wavelength of light emitted when an electron falls from n equals 4 to n equals 1 than when an electron falls from n equals 2 to n equals 1?
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
What does incident light that falls on an object do to the electrons in the atoms of an object?
When a photon of energy falls on an electron bound inside an atom, the electron absorbs the energy and is emitted from the atom.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
How do you generate light?
Light is generated when photons are emitted from an atom. This occurs when an electron on one energy level of an atom falls to a lower energy level.
What happens when ann electron moves to a higher energy level?
It falls back to its ground state, emitting light of a particular wavelength and color.
When an electron drops from a higher energy state to a lower energy state?
A photon is emitted when an electron falls from a higher to lower orbital. A photon is an elementary particles, the quantum of light and all other forms of electromagnetic radiation.
When an electron falls from a higher energy level to a lower energy energy level how is the energy released?
The energy is released as electromagetic energy and each transition in each atom has its own wavelength for the light emitted.
What has to happen before you can move to a new energy level in the electron cloud?
When an electron falls from a higher to lower energy level, it emits a photon. Atom will emit only light with a wavelength (color).
What happens to the energy of the electron as it falls down the electron transport chain?
pie
What happens as an electron falls from a higher level to a lower level in an atom?
it falls in 89
What is the difference between an absorption and an emission spectrum?
Absorption spectrum is a gap in the overall spectrum. It happen when light makes an electron jump to a higher orbital and light energy is absorbed. Emission spectrum is light emitted at particular wavelengths (where the absorption spectrum gaps are). It happens when an electron falls from a higher orbital and emits light energy in doing so.
