What physics principle is used when pumping your legs in rhythm with the natural frequency of a swing?
Resonance - when pumping a swing in rhythm with its natural frequency, it produces larger amplitudes.(def. - occurs when the frequency of a vibration forced on an object matches the object's natural frequency and a dramatic increase in amplitude occurs)
When two objects vibrate at the same frequency what occurs?
resonance
What type of emission occurs?
It could be spontaneous, carbon, nocturnal, pollutant etc., depending on what's doing the emitting.
How often a wave occurs is the waves?
You really shouldn't be looking for the answer of a test or homework on the computer. But the answer is How often a wave occurs is the waves frequency.
When two objects such as marimba bars and columns vibrate at the same frequency what occurs?
resonance
If considering two different atoms explain the spectral lines?
Spectral lines are bright or dark lines in an otherwise continuous or uniform spectrum. They are caused by an excess (emission lines) or deficiency (absorption lines) of observed photons within certain frequency ranges. Absorption lines usually come from a background continuum; photons are absorbed when passing through matter to the observer. Absorption occurs when an electron within an atom absorbs a photons energy and is bumped up to an excited state. Emission lines usually come from hot gases; photons are emitted from these gases and reach the observer. Emission occurs when an electron within an atom falls back down to it's ground state and releases energy in the form of a photon.
Is light emitting diodes emit visible light when forward biased?
It depends on the particular LED. Some of them emit infrared light. But, yes, emission occurs when forward-biased.
The number of times a data occurs?
the answer is frequency. the answer is frequency.
How does the spectral interference differ in inductively-coupled plasma mass spectrometry compared to flame?
Spectral interference occurs when spectral lines overlap. Inductively-coupled plasma mass spectrometry has more spectral interference as its higher energy allows more electron transitions.
What is the meaning of the natural frequency of a body?
The Natural frequency is the frequency at which Resonance(maximum amplitude) occurs.
What is the number of times that an event occurs?
frequency
How often a thing occurs is called?
frequency
Is daily an adverb of frequency?
Yes. Adverbs of frequency tell how often something occurs.
The number of times an allele occurs in a gene pool?
Think frequent. More of the allele in the populations gene pool and there is a change in the alleles frequency. Some goes for less of the allele.
When is fluorescence strong?
Flluorescence is strong in systems in which emission occurs from the state with the lowest energy.
What occurs if the frequency of a force applied to system matches the natural frequency ofvibration of the system?
Resonant
What is the difference between spontaneous emission of radiation and stimulated emission of radiation?
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
