What is optical absorption spectroscopy?
This is the absorption of photons with specific wavelengths by different types of materials.
Which substance is a green molecule in chloroplast that absorbs photons?
Chlorophyll.
Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
Is there dipole moment present in Raman spectroscopy?
Essentially Raman spectroscopy focuses incident light upon a target. The photons of the incident light can scatter elastically or inelastically upon striking the molecules of the target molecule. Either way, the dipole moments of the molecules involved are temporarily increased and energy is emitted.
What is the difference ultraviolet and infrared spectroscopy?
FTIR spectroscopy cannot be used to detect all the vibration modes in a molecule. It can be used only to study the non-symmetrical vibrational state in an atom. Using Raman Spectroscopy one can study the symmetric stretch of the atom. For example the symmetric stretch of CO2 which cannot be studied by FTIR can be studied by Raman Spectroscopy. Here the permanent dipole moment of the molecule during a vibrational cycle does not change as it does not involve polarization. As a result, this mode cannot absorb infrared radiation. In many instances, vibrational modes that are not observed by infrared absorption can be studied by Raman spectroscopy as it is the result of inelastic collisions between photons and molecules

What substance has the most fast moving particles?
Photons

Chlorophyll.
Why does quinine glow when placed under black light?
A substance such as quinine glows because when absorbed light photons release photons of another wavelength. When the absorbed photons are in the ultraviolet range and the triggered emission is in the visible spectrum, a substance will glow under black light.
What is photo luminescence?
it is not photo luminescence it is photoluminescence.Photoluminescence (abbreviated as PL) is a process in which a substance absorbs photons (electromagnetic radiation) and then re-radiates photons.
Why is there no substance that convert visible light to UV?
UV photons have more energy (less wavelength, higher frequency) than visible light photons. It is possible to convert photons to ones with less enery, but not the opposite.
Is sunlight made up of elements?
No. Any kind of light is not made up of elements, but rather of photons, which have no rest mass.
Is there dipole moment present in Raman spectroscopy?
Essentially Raman spectroscopy focuses incident light upon a target. The photons of the incident light can scatter elastically or inelastically upon striking the molecules of the target molecule. Either way, the dipole moments of the molecules involved are temporarily increased and energy is emitted.
The photoelectric effect refers to what?
The waves have to be considered as made up of small packets of energy bundles called as quanta (photons). As these photons fall on a substance they eject electrons right from the surface.
What is color absorption?
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum.
Light is made of photons that have no rest mass and exist as an electromagnetic ripple in space-time No elements and no atoms?
Yes, it is true; no atoms of the elements in the light.
What is the green substance in plant Cells and what does it do?
Chlorophyll transforms photons [except those of Green] of Sunlight into Glucose sugar.
