excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state.
emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
What else can I help you with?
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
How energy is emitted when an atom returns to the ground state?
When an atom returns to the ground state, it releases the excess energy in the form of light. This process is known as emission of photons. The energy of the emitted photon is determined by the difference in energy levels between the initial and final states of the atom.
What does the electron produce when they change energy levels?
When electrons change energy levels, they emit light or energy in the form of electromagnetic radiation. This emitted light can have specific frequencies or colors, depending on the difference in energy levels that the electron undergoes.
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
Sketch an atom emitting light. Does the electron end up in a higher or lower orbit. Repeat for an atom absorbing light?
When an atom emits light an electron has fallen from a higher orbit to a lower orbit. The amount of energy the emitted photon has will equal the energy difference between the initial and final orbits.
Why do electrons emit light when they fall down to their ground state?
When electrons fall down to their ground state, they release energy in the form of photons of light. This is because the energy difference between the higher energy state the electron was in and the ground state is emitted as light. The wavelength of the light emitted depends on the specific energy difference between the two states.
Is it true that Brightness ratio is the difference in light intensity between brightest white and darkest black produced by a monitor?
No, the brightness ratio is the numerical difference between the brightest and darkest light levels emitted by a display. It is a measure of the display's dynamic range.
What is the difference between kelvin and lumens in terms of measuring light output?
Kelvin measures the color temperature of light, indicating whether it is warm or cool. Lumens measure the brightness of light, indicating how much light is emitted.
What are coherence?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
The color of light emitted by an atom is most closely related to?
The color of light emitted by an atom is most closely related to the energy difference between the atomic energy levels involved in the transition. Each element has specific energy levels that determine the color of light it emits when an electron transitions between them. This relationship follows the principles of quantum mechanics.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
What is the candle power of the 4157 light bulb?
whats the difference between a 3157 and a 3457 bulb
What is the difference between candela, lumens, and lux, and how do they each measure the brightness or intensity of light?
Candela measures the intensity of light emitted in a specific direction, lumens measure the total amount of light emitted by a source, and lux measures the amount of light that falls on a surface. Candela is used for directional light sources like flashlights, lumens for overall brightness of a light source, and lux for the brightness of light on a surface.
What is the relationship between the Kelvin temperature and the color of light emitted by an object?
The relationship between the Kelvin temperature and the color of light emitted by an object is that as the temperature increases, the color of the light emitted shifts from red to orange, then to yellow, white, and finally blue as the temperature gets hotter. This is known as blackbody radiation, where higher temperatures correspond to shorter wavelengths and bluer light.
What is the relationship between the light emitted by an atom and the energies of the electrons in the atom?
Light Energy increases as you move down the period table among the alkali group.
Quanta of light emitted from 1 electron drops from the 7th to 2nd energy level?
When an electron drops from the 7th to the 2nd energy level in an atom, it emits a photon of light. The energy of this photon corresponds to the difference in energy between these two levels. The amount of energy difference is specific to the atom involved, and the photon emitted will have a specific wavelength and color based on this energy difference.
What is the relationship between the light emitted by an atom in the energies of the electrons in the atom?
The more energy levels the electron jumps the more energy the emitted light will have. The more energy you have the shorter wavelength there is.
