What is the difference between emitted light and exciting light?

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.

Emitted light is light that is produced by a source, such as a light bulb or the sun, while exciting light is light that is used to excite a material or substance, causing it to emit light in response. Exciting light is typically of a higher energy level than the emitted light.

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 emitted by a bulb is not monochromatic because it contains a range of frequencies and wavelengths. Bulbs generate light through thermal radiation, where the atoms in the filament vibrate at different energies, leading to a broad spectrum of emitted light. This results in a mix of colors and wavelengths in the light emitted by the bulb.
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, the electron transitions from a higher energy level to a lower energy level within the atom, releasing energy in the form of light. The emitted light has a wavelength corresponding to the energy difference between the two energy levels involved. When an atom absorbs light, the electron absorbs the energy of the incoming photon and jumps to a higher energy level within the atom, moving to a more excited state.
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 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.
What is the candle power of the 4157 light bulb?
The 4157 light bulb typically has a candlepower of around 30 to 35. Candlepower is a measure of the intensity of the light emitted by a source in a specific direction.
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 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.
What is the difference between radiance and luminance?
Radiance is the amount of light energy emitted or reflected from a surface per unit solid angle, regardless of where it is being viewed from. Luminance, on the other hand, is the amount of light energy emitted or reflected from a surface per unit area as seen from a given viewing angle. In simpler terms, radiance is the total light output, while luminance is how bright it appears to an observer.
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 quantum leaps would be associated with the greatest energy of emitted light?
Quantum leaps between energy levels that are farther apart would be associated with the greatest energy of emitted light. This is because energy and wavelength of emitted light are inversely proportional, so larger energy differences result in shorter wavelength (higher energy) light being emitted.
