Yes. When electrons go from a higher energy orbital to a lower one, they release photons (ie: light).
Excite electrons
Visible light. It has a higher frequency so more energy.
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.
Tungsten emits light when heated because of its high melting point and conductivity. As it heats up, the tungsten atoms gain energy and begin to vibrate, causing the release of photons in the form of visible light. This light emission is what is commonly observed in incandescent light bulbs and other tungsten-based light sources.
Concrete absorbs visible light and re-radiates it as infrared energy
Its electrons are excited to a higher energy state in the flame, and then they immediately release that energy, which is visible as yellow light.
Excite electrons
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 you add energy, electrons move to a higher energy level (orbit). WHen they come back down, they release energy. If that energy (wave length) is in the visible light range, we see color.
When an atom releases energy in the form of visible wavelengths of light, it indicates that an electron in that atom has gone from an excited energy level, back down to a lower energy level.
no it depends on the energy level the electrons are jumping down to
Visible light. It has a higher frequency so more energy.
Light energy is a form of energy that is associated with visible light.Examples: The sun, , a lamp, or a lightbulb,, they are all forms of visible light.
exactly what you said its called visible light.
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.
Electrons are released from chlorophyll and create an electron hole , it is just like formation of a positive ion or ionization .
