An atom that undergoes excitation and de-excitation emits?
A quanta of light (one photon).
How atomic excitation lead to concept of laser?
How atomic excitation lead to concept of laser?
What is metastable ion in mass spectroscopy?
An ion that is formed with sufficient excitation to dissociate spontaneously during its journey from source to detector is called metastable ion.
In synchronous motor theory is excitation current the same as field current?
yes. excitation current is same as field current to my knowledge
What happens to chromosomes during anaphase?

An atom that undergoes excitation and de-excitation emits?
A quanta of light (one photon).
If the excitation of generator changes what happens to the terminal voltage?
By Decreasing the excitation voltage the terminal voltage will decrease and similarly by increasing the excitation voltages the terminal voltage will also increases.
What happens if excitation fails in parallel oprating generator?
when excitation fails,Reactive power will be supplied by the system to which the generator is connected and generator will work as induction generator and its speed will rise a little. generator which was in over excitation mode will work in underexcitation.but there is under excitation limit which should not be reached so we should detect loss of excitation and trip generator
What rhymes with ovation?
Nation, automation, celebration, excitation, deliberation, excitation, penetrationcelebration, excitation, deliberation, excitation, penetration
What best describes the events of excitation in excitation-contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.
What happens to the resistance when the frequency is doubled?
Impedance of a coil or a capacitor does depend on the excitation frequency,but resistance has no relationship to frequency.
What are the Applications of excitation transfer theory?
Excitation theory is a misattribution of arousal.
What is a type of light emission that relies upon a delay between excitation and de-excitation providing an afterglow?
You are talking about a glow-in-the dark material. It is called phosphorescent. The same idea, light being absorbed and re-emitted at a different frequency - has two main types. If it happens immediately, it is "fluorescent" (think highlighters in a black light) If there is a delay, it is "phosphorescence." Both effects and the delay in the second, are the result of quantum mechanics.
Excitation-transfer theory by zillmann?

What is meant by excitation frequency?
Excitations frequency is the frequence of the electron making a quantum spring from a higher level to an lower. In cemical reactions the excitations happens alle the time, an it happens in a frequence.
What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Heart excitation originates in the?
Heart excitation originates in the sino-atrial node.
