This would consist of several series of lines corresponding to the energies of electron transitions. They are bright lines for an emission spectrum and dark for absorbtion.

What is example of signifier and signified?
Signifier is the image....signified is the concept behind the image
What part allows you to view the image on the stage and contains the ocular lens?
The body tube of a compound optical microscope contains the ocular lens which focuses the image from the objective lens and allows you to view the image on the stage.
Labled Parts of the bunts and burner?
the different parts of a Bunsen burner are:
Why the red is red?
It has to do with our brain interpretation of the visual stimulus and how our eyes perceive and communicate to the brain the image of the light spectrum that is visible. Red things are red because of the specific spectrum of light that is being reflected from the item and our eyes' (and brain's) interpretations of that visible spectrum. For example, a matt finish black item reflects back no light, therefore looks black, but white colors reflect back all the light, therefore are seen as white (a mix of a full spectrum of colors reflected is perceived as white). Red colors only reflect back the red light, and absorb the other colors in the spectrum, so they are not visible to our eyes. Interesting tidbit: Very recent studies have indicated that different individuals see colors differently and in some cases, so do groups of people, such as a specific tribe of people who participated in one of the studies. That tribe not only has no word in their language for the color blue, they also can discern no difference between the color green and the color blue when side by side. As indicated above, these are very recent 2012 results and more is still being studied based on these results about how we see color. It is becoming more likely that our brain has as much or more to do with our sensing of color than our eyes. Keep an eye out for more results on this interesting new finding.
A converging lens of focal length f produces a real image of a real object when the object is what?
farther then f from the lens
What is the Latin meaning of spectrum?
The Latin meaning of spectrum is image or apparition. Spectrum was used to designate a ghostly optical afterimage by Goethe in his Theory of Colors and Schopenhauer in On Vision and Colors.
What does spectograph do?
A Spectograph breaks light into colors and produces and image of the resulting spectrum.
Does the color of the eye effect negative after image?
no negative color is based off the color spectrum and is the same in all setting including the retina's after image
As you move from left to right across the electromagnetic spectrum in the image the wavelength becomes?
longer.
What has the author Cecil Leeburn Wilson written?
Cecil Leeburn Wilson has written: 'Comprehensive analytical chemistry' 'Micro-tests for elements in organic compounds' 'CS1' -- subject(s): Mathematical models, Transistors 'Effect of resolution and image quality on combined optical and neural network fingerprint matching' -- subject(s): Fingerprints, Fourier transform optics, Image quality, Imaging systems 'The variation with temperature of the absorption spectrum of solid europium chloride'
Is a procedure in which a radioactive substance is placed within the body to enable visualization of a bone via the image produced by the emission of radioactive particles?
Bone Scan
What is a brain-imaging method in which radioactive glucose is injected into the subject and a computer compiles a color-coded image of the activity of the brain?
PET or positron emission tomography
What is spec imaging?
It is not "spec" imaging but SPECT (single proton emission computed tomography) imaging. It uses gamma rays and provides a true 3D image.
Why you turn ON the temperature regulator of the CCD before taking images or spectrum?
Due to the way CCD's work the higher the temperature the more random noise it will collect in an image. By reducing its temperature it increase the accuracy of an image.
Why is the CCD important?
A charge-coupled device (CCD) is a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel (picture element) in the image is converted into an electrical charge the intensity of which is related to a color in the color spectrum.
Cross-power spectrum of two fourier transform images?
It's (I1./I2*)/(|I1./I2*|), where I2* is the complex conjugate of the Fourier transformed Image 2
Name all the categories of the EM spectrum?
The categories of the electromagnetic (EM) spectrum, in the ascending order of their frequencies are:RadioMicrowaveInfraredVisibleUltravioletX-rayGammaHence, Radio waves have the lowest frequency and the longest wavelengths while Gamma rays have the highest frequency and the shortest wavelengths.(check related link for an image)
