What is the emission of colored light rays during exposure to ulraviolet light?

Fluorescence. It happens when atoms' electrons absorb light at one frequency and emit at other (usually lower) frequencies. Sometimes two photons are absorbed by the same electron, and emitted as a single higher frequency, but this is not common.

Why spontaneous emission is incoherent?
During spontaneous emission, photons are emitted randomly and hence they will not in phase with each other. such light is irregular and mixed of different frequencies,direction and duration.therefore the beam of light emitted is incoherent.sudhir tiwari.sharda university
What is a star's emission spectrum?
The emission spectrum of a star is the spectrum of frequencies for emitted electromagnetic radiation during the transition of an atom's electrons from a high-energy state to a low-energy state. The emission spectrum can differ depending on the temperature and composition of the star.
How are land breeze caused?
i think the answer to this question is just that during the day, when the temperature is hot (sun) the heat emission that comes directly from the sun makes the land gets hot.
How many waves from a single ray of ultraviolet light with a frequency of 1.2x1015 Hz does your skin absorb during a one hour exposure?
a frequency of 1.2x10^15 Hz
Is light colored roof or a dark colored roof more energy efficient?
Most believe that the only function of a roof covering is to provide a material to shed water, but of equal importance is its ability to provide thermal protection. In a house with a cathedral ceiling, the roof forms the ceilings of the rooms below. A dark colored shingle will affect the interior environment by absorbing solar heat from the sun during the day. This same roof, on a clear, cool night will transmit more heat from the house than would a light colored roof. A white or nearly white roof will reflect solar radiation during the day and will not radiate much heat at night. Unfortunately the roof has to stay relatively clean if it is to function properly.
The emission of colored light rays by a substance during exposure to ultraviolet light?
fluorescence

What is the English term swapnadosh?
The English term for swapnadosh is "nocturnal emission" or "wet dream". It refers to the involuntary release of semen during sleep, typically during dreams or sexual fantasies.
Working principle of atomic emission spectroscopy?
An emission spectrum is the spectrum of frequencies of the electromagnetic radiation emitted (by an atom or molecule) during a transition from a high energy to a low energy level.
What is the importance of emission of electrons from chlorophyll during photosynthesis in plants?
they are carrying energy. that is why itis important.

What has the author Samson S Lee written?
Samson S. Lee has written: 'Acoustic emission during unloading of elastically stressed magnesium alloy' -- subject(s): Quality control, Acoustic emission
When does Thermionic emission occur during x-ray production?
thermionic emission occurs when the filaments are heated to a certain degree, causing the electrons to boil off and form a space charge or electron cloud.
Can a single short time exposure to UV light cause any harm to human body?
That would depend on its intensity during the brief exposure.
