What analyzes an objects spectrum?
A spectrum analyzer or spectral analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. It may also measure the power spectrum. There are analog and digital spectrum analyzers: * An analog spectrum analyzer uses either a variable band-pass filter whose mid-frequency is automatically tuned (shifted, swept) through the range of frequencies of which the spectrum is to be measured or a superheterodyne receiver where the local oscillator is swept through a range of frequencies. * A digitalspectrum analyzer computes the discrete Fourier transform (DFT), a mathematical process that transforms a waveform into the components of its frequency spectrum. http://en.wikipedia.org/wiki/Spectrum_analyzer
Why can radio waves pass through walls but light cannot?
Radio waves are longer on the electromagnetic spectrum and can penetrate objects because they are less dense. Visible light and infrared light are shorter and therefore too dense to pass through objects.
Why is the electromagnetic spectrum such as radio waves used to study space?
Most stars and many other objects in space emit radio and microwave radiation. Even the big bag emitted electromagnetic radiation.
Is light part of the radio spectrum?
No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
The full range of frequencies of electromagnetic radiation is called?
That would be a spectrum or band.

What is the function of a spectrum analyser?
A spectrum analyzer is an instrument that analyzes the spectrum of both known and unknown signals. It has several functions, including detecting new signals, measuring power and energy, isolating frequencies, and isolating signals.
What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?
Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
What will happen to an objects spectrum as the object moves away from you?
the spectrum change with direction, either from you or away
Why do shiny objects reflect light spectrum?
because they have no darkness
Which part of electromagnetic spectrum is emitted by warm objects?
IR, mostly.
How are spectrums used to study?
Astronomers use the light spectrum of distant objects to determine the chemical composition of those objects. Each element on the period table gives off a different spectrum, and by looking through a spectrometer an astronomer can read the spectrum and figure out what that object is made up of to gain better understanding of our universe.
Who is the person who analyzes the organization of civilization and societies?
An anthropologist analyzes the organization of civilizations and societies.
Why do some objects appear brown?
Brown objects reflect som light in the yellowish/orangish part of the spectrum. "dirty" orange is called "brown".
How does a radio telescope see objects which are too dim for an ordinary telescope?
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
Who analyzes MRI exams?
A radiologist is the person who analyzes MRI exams.
What is the plural of analyze?
The plural of analyze is analyzes. As in "the expert analyzes the data".
