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 are the two types of spectrum?
The two types of spectrum are continuous spectrum, which shows a continuous range of colors with no gaps, and line spectrum, which consists of distinct lines of color separated by gaps.
If 5.50 mol of butane are reacted how many moles of water vapor are produced?
Each mole of butane, which has formula of C4H10, contains 10 moles of hydrogen atoms. If the butane is completely combusted, all of the hydrogen in the butane is converted in water, with the formula H2O. The amount of water vapor will accordingly be 5.50 X 10/2 = 27.5.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
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.
What is the spectrum of a signal?
2Fb/M
What is amplitude spectrum?
The amplitude spectrum is a plot that shows the distribution of amplitude values of a signal across various frequencies. It provides information about the strength or magnitude of each frequency component present in the signal. The amplitude spectrum is commonly used in signal processing and audio analysis to characterize the frequency content of a signal.
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.
What does the butane phase diagram illustrate about the different states of matter that butane can exist in under varying temperature and pressure conditions?
The butane phase diagram shows how butane can exist as a solid, liquid, or gas depending on the temperature and pressure. It illustrates the boundaries between these states and the conditions where each state is stable.
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.
What is an audio spectrum analyzer?
Audio frequency spectrum is measured in Hertz's (Hz) and tells the range of audible audio. The human hearing range is usually 20-20000Hz, but especially the audibility of the top end of the spectrum declines with age. Most software analyzers measure between 0 Hz and 16000-24000kHz
What is the difference between an absorption spectrum and a standard curve in analytical chemistry?
An absorption spectrum in analytical chemistry shows how a substance absorbs light at different wavelengths, while a standard curve is a graph that relates the concentration of a substance to its measured signal, helping to quantify the amount of that substance in a sample.
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.)
What are some comparisons with a absorption spectrum and a continuous spectrum?
An absorption spectrum shows dark lines at specific wavelengths where light has been absorbed by a substance. A continuous spectrum shows all colors/wavelengths with no gaps, like the rainbow. The main difference is that the absorption spectrum has specific dark lines while the continuous spectrum is smooth and uninterrupted.
