What is chromatic aberration?
How does it affect sharpness of an image?
Homework Answers
Chromatic aberration is the inability of a lens to focus different colors in exactly the same place. In simple words, when colors are incorrectly refracted by the lens, a color mismatch will result means the colors will not combine in the a way they should. This is when wavelengths of color are focused at different positions in the focal plane.
It affects the sharpness of an image in a way that we get to see some border shades of red, cyan or blue colors where light is not properly focused. Usually, this happens on the edge of an object under focus.

Chromatic aberration comes from the fact that different wavelengths of light travel at different speeds through the material of the lens; that is, they have different indices of refraction, a property known as dispersion. This means that a lens, in effect, has different focal lengths for different wavelengths of light. Consider a lens made to the following specifications: focal length for red light fred=19.57cm, focal length for blue light fblue=18.87cm. Part A Consider an object 5.000cm tall placed a distance...

I'm wandering firstly how the number of photons affect the contrast and density of the image? Secondly how the voltage, tube current, target material and filter affect the image and the contrast and density. That is simply it. I am not asking how these factors affect the production of x rays, what I am asking is how these factors affect the x rays absorption through matter and consequent production of an image on the film? I don't understand what you...
