Yes. When electrons go from a higher energy orbital to a lower one, they release photons (ie: light).

Why is there no substance that convert visible light to UV?

There is no substance that can directly convert visible light to UV because the energy required to promote electrons from the visible light energy levels to the UV energy levels is too high within a single step. The energy levels of the electrons in UV are simply too far apart from those in visible light for a direct conversion to occur.


Wavelength of electrons are what percent visible in the white light?

The wavelength of electrons is about 10,000 times shorter than the wavelength of visible light. This means that electrons are not visible in white light as their wavelengths are outside the visible spectrum.


What is the basic mechanism responsible for emission of visible radiation in an LED?

by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.


During photosynthesis visible light has enough energy to?

During photosynthesis, visible light has enough energy to excite electrons in chlorophyll molecules within the chloroplasts of plant cells. This excitation of electrons allows them to undergo a series of reactions that eventually produce ATP and NADPH, which are essential for the synthesis of glucose and other organic compounds.


What were electrons doing when the green light was emitted?

When green light is emitted, electrons are transitioning from higher energy levels to lower energy levels within an atom. This release of energy appears as light in the green wavelength range.

Why is ultraviolet light effective in making certain materials fluoresce?

Ultraviolet light has higher energy compared to visible light, which can excite electrons in certain materials to a higher energy state. When these electrons return to their original state, they release energy in the form of visible light, causing fluorescence.


When electrons are excited out of their orbitals do they release light energy?

It takes energy to get those electrons up out of their orbitals. It is when they "fall back" and return to their orbitals that they release energy. The energy released will be electromagnetic energy, and if the energy is high enough (but not too high), it will appear as visible light. This is what is happening in a fluorescent tube when it is turned on and emitting light.


When excited electrons return to lower energy levels what is released?

When excited electrons return to lower energy levels, they release energy in the form of photons. This process is known as emission of light or fluorescence. The energy of the emitted photons corresponds to the energy difference between the higher and lower energy levels of the electrons.


How does uv light cause the TLC spots to appear?

UV light causes the compounds on a TLC plate to absorb the light, which excites the electrons in the molecules to a higher energy state. When the electrons return to their original state, they release energy in the form of fluorescence and produce visible spots on the TLC plate.

What is light produced?

A filament is heated by an electric current and photons are emitted.


How do electrons jumping between energy levels contribute to the emission of light in atoms?

When electrons jump between energy levels in atoms, they release energy in the form of light. This emission of light occurs when electrons move from higher energy levels to lower energy levels, releasing photons in the process.


Why is visible light given off when a salt such as sodium chloride is exposed to a flame?

When a salt like sodium chloride is exposed to a flame, the high temperature causes the electrons of the metal ions (such as sodium) to become excited. As the electrons return to their ground state, they release energy in the form of light. This visible light is the characteristic color emitted by the specific metal ions present in the salt.
