What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
Which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?
The red line in the second graph shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum.
Is the color spectrum simply a small segment of the electromagnetic spectrum?
Yes, visible light (the color spectrum) is a tiny range of the full range of electromagnetic waves. In the related Wikipedia link, there is a picture that shows the colors 'crammed in' to a small range of the spectrum.
Why is electromagnetic spectrum called continuous spectrum?
The EM spectrum may, in fact, not be continuous, but quantised wrt the frequency of the emitted photons that comprise the spectrum. This implies that the frequency of oscillation of the emitting quantum mechanical system is quantised. To establish beyond doubt the continuity, or otherwise of the EM spectrum would require the accutate measurement of the frequency of individual photons. Given the magnitude of Planck's Constant (~ 6.26 x 10^-34 Js) the Planck-Einstein-Schrodinger equation, E = hv shows that, for a single photon a measurable signal cannot be generated at low frequencies (~ a few Hz), whilst at high frequencies (~ a few GHz) any quantisation of the frequency of the photon would not be observable.
Why was the study of line spectra useful in the discovery of new elements?
The bright line spectrum is useful because it shows us the different particles in the elements.
Is sawtooth signal analog?
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
What can be determined by studying a solar spectrum?
Dark lines of the absorption spectrum give the elemental composition of the chromosphere, information about the magnetic field and density of the surface. The peak of the continuous spectrum gives the surface temperature. The Doppler Effect shows the movement of the sun and the sun's surface. Splitting of spectral lines verifies the magnetism of sunspots.
What does the absorption spectrum of an atom show?
The absorption spectrum of an atom shows that the atom emits that spectrum which it absorbs.
What is bandpass signal?
A bandpass signal, xc(t), is a signal whose one-sided energy spectrum is both: 1) centered at a non-zero frequency, fC, and 2) does not extend in frequency to zero (DC). The two sided transmission bandwidth of a signal is typically denoted by BT Hertz so that the one-sided spectrum of the bandpass signal is zero except in [fC − BT /2,fC + BT /2]. This implies that a bandpass signal satisfies the following constraint: BT /2 < fC. Fig. 1.1 shows a typical bandpass spectrum. Since a bandpass signal, xc(t), is a physically realizable signal it is real valued and consequently the energy spectrum will always be symmetric around f = 0. The relative sizes of BT and fC are not important, only that the spectrum takes negligible values around DC. In telephone modem communications this region of negligible spectral values is only about 300Hz while in satellite communications it can be many Gigahertz.
Does temperature affect whether or not a spectrum shows?
Temperature does affect whether or not a spectrum shows up and how. The higher the temperature is, the more red the spectrum will appear, while the cooler it is, the more blue it will appear.
How do you find the fundamental frequency of a sample using a spectrum analyzer?
Looking at the spectrum displayed on the spectrum analyzer, the fundamental will generally be the left-most vertical spike above 0Hz. However, to qualify as the fundamental, this tone must have a specific harmonic relationship to the other components of the sampled signal. The relationship is that every upper tone in the signal should be an integer-multiple of the frequency of the fundamental. Thus, if you find three spikes, one at 200Hz, one at 300Hz and one at 400Hz, the 200Hz tone is not the fundamental. That would be a tone at 100Hz, and the signal you are looking at has a 'suppressed fundamental'. Likewise, if the signal described above also had a spike at 50Hz, this _could_ be the fundamental, where the second harmonic (at 100Hz), third harmonic (at 150Hz) fifth harmonic (at 250Hz) and all harmonics above the sixth are being suppressed. An additional worthy test is to turn off the signal and look at the spectrum. If there are signal components displayed that don't relate to the sample, they would show up after the signal is removed. (I.e., do an analysis of silence, and anything that shows up needs to be subtracted or discounted from the signal spectrum.)
Which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?
The red line in the second graph shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum.
What kind of spectrum shows all the colors?
a white spectrum because white is made up of all colors.
What is a continues spectrum?
A continuous spectrum shows all of the colors produced when white light passes through a prism.
